Question

-4x + 2y = 8
4x – 3y = -10
i am very confused on what to do i have some of this worked but i am stuck

Answer 1

do you have to find both the x and y values?

Answer 2

What methods have you learned so far to solve systems of equations?

Answer 3

yes do you want me to show you what i already have worked?

Answer 4

yes please it will help a lot.

Answer 5

-4x+2y=8
4x-3y=-10

-4x+4x=0
2y-3y=-y

8-10=-2

-y=-2
y=2 and then i dont know what else to do or how to check my work

Answer 6

now plug in y=2 to one of the two equations and solve for x. For example

-4x+2y=8 , y=2
-4x+2(2)=8
-4x+4=8

Can you do the rest?

Answer 7

Your solution will be

x=? , y=2

Answer 8

x=? is whatever you find for x

Answer 9

x=-1 and positive 4

Answer 10

do you know how to do a check step?

Answer 11

-4x + 2y=8
answer =y/2 -2

Answer 12

4x – 3y = -10
answer = x =3y/4 -5/2
