**Weegy:** For the following system, use the second equation to make a substitution for x in the first equation. x + 2y = 7, x + 5 = 3y, the resulting equation is 3y - 5 + 2y = 7. x + 5 = 3y; x = 3y - 5; 3y - 5 + 2y = 7

**User:** The multiplication property of equality could be used to solve which of the following equations?
4x = 5
x + 5 = -4
= 1
(x + 5)(4x - 1) = 0
