14x – y = –10
7x + 2y = 15

Answer 1

Solve for x, and then subsitute the value of x into the equation.

Answer 2

Add y to the right side then divide the right side by 14.

Answer 3

You should get x=y-5/7

Answer 4

Plug that into the second equation.

Answer 5

A) 14x – y = –10
B) 7x + 2y = 15
Multiply equation A by 2.
Add this to equation B.
You now have an equation solved for x and now you you can solve for y.
