For the following system, use the second equation to make a substitution for x in the first equation.

x + 5y - 10 = 0
x = 2y - 8

What is the resulting equation in simplest form?

-3y - 18 = 0
3y - 18 = 0
7y - 18 = 0

jhonyy9 · Answer

in the first equation in place of x write 2y-8 so will get 

2y-8 +5y -10 = 0 make calculi and see what choice will get - ok. ?
