Question

What is the x-value of the solution to the system of equations shown

below?



-3

-1

1

3

Answer 1

-3

Explanation:

you can use elimination to remove y from this equation

your first equation will be

4x+10y=-2; and you can multiply the other one by -10

30x-10y=-100

if you add the two equations, 10y and -10y will cancel out and you'll get

34x = -102

divide both sides by 34

x=-3
