what is the solution to this system of equations?
5x-y=40
y=2x-4
A) 20, 12
B) -20, 12
C) 12, -20
D) 12, 20
Answers
5x - (2x - 4) = 40
Solve for x
5x - 2x + 4 = 40
3x = 36
x = 12
Plug in x for either equation
y = 2(12) - 4
y = 24 - 4
y = 20
X = 12 and Y = 20, so D
{ solve simultaneously }
rearrange equation to make y the subject
5x-y=40
y=5x-40
Sub y=5x-40 into the second equation given ( y=2x-4 )
5x-40 = 2x-4
Solve normally to find x
x = 12
Sub x=12 into y=5x-40
Solve normally to find y
y = 20
Therefore, answer is D) 12, 20

Answer:
x = 30
Step-by-step explanation:
The sum of the exterior angle and interior angle of a polygon = 180°
Then the 2 unknown interior angles are
180 - 2x and 180 - (3x - 20) = 180 - 3x + 20 = 200 - 3x
The sum of the 4 interior angles of a quadrilateral = 360°
sum the 4 interior angles and equate to 360
2x + 2x + 10 + 180 - 2x + 200 - 3x = 360 , that is
- x + 390 = 360 ( subtract 390 from both sides )
- x = - 30 ( multiply both sides by - 1 )
x = 30

Two systems of equations are shown:
System A System B
3x + 2y = 3 −x − 14y = 1
−2x − 8y = −1 −2x − 8y = −1
Which of the following statements is correct about the two systems of equations?
A.)The value of x for System B will be one-third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.
B.) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
C.) They will have the same solution because they represent the same lines when plotted on the coordinate axes.
D.)They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

3x-9y=-7 ; 2y-6x=8 elimination
Answers
Answer:
x=-29/24
y=3/8
Step-by-step explanation:
3x-9y= -7 ---A
2y-6x= 8----B
multiply eq A by 2
6x-18y=-14
-6x+2y=8
Add both equations, so you eliminate x since 6x+(-6x) = 0
-18y+2y= -16y
-14+8=-6
so you have
-16y=-6
y=3/8
now substitute this back to eq B, (you can use eq A as well if you like)
2(3/8)-6x=8
3/4-6x=8
-6x=29/4
x=-29/24

Answer: 4x + 3 = 39
Step-by-step explanation:
Because you don't know how much each pizza costs, you can write it as x.
You multiply x by 4 to get 4x and add 3 because thats how much the chips cost.
That added up should equal 39 because thats how much he spent.
Answer: The answer is C ( 4x + 3 = 39 )
Step-by-step explanation:
4 = number of Pizzas. x = price of pizza. 3 = price of chips. 39 = total of 4 pizzas and chips together.
1) 4x + 3 = 39
2) 4x = 39 - 3
You will seperate the variable(4x) and the constants(3 and 9) So, you move (+3) to the other side making it negative. Then, you subtract (39-3) which will equal to (36)
4) 4x = 36
5) x = 36/4
You want to move the coefficient(4) to the other side. Thus, will make it a division becaue the oppisite of multiplication is division. So you cancel it out from x because 4/4 is 1.
6) x = 9
You divided 36/4 which will equal to 9
7) 4(9) + 3 = 39
