Question

For the followign system of equations, what is the x- value of the solution?
-x+2y=6
6y=x+18
And please show your work with this

Answer 1

-x+2y=6
-x=6-2x
x=-6+2y

Answer 2

then substitute it for x in the next

Answer 3

6y =(-6+2y)+18

Answer 4

solve for y
6y= 12+2y
4y=12
y=3

Answer 5

The solution will be where their values intersect

Answer 6

then with the y value sub it into one.
-x+2y=6
-x+2(3)=6
-x+6=6
x=0
