Question

What is the solution of the system of equations?

10x+10y=-5
4x=-5y

Solve by substitution.

Answer 1

rewrite the2nd equation by dividing both sides by -1

so

-4x = 5y

and substitute into the 1st equation

remember 10y = 2(5y)

hope this helps

I'm confused but thank you

Answer 3

Still need help

Answer 4

10x + 2(-4x) = -5

collect like terms then solve for x
