# Solve for y:
5x + 3y = 22
y = 2x

Question:

A
4

Explaination

First, plug the definition of y from the second equation into the first equation. 5x + 3(2x) = 22 Simplify and solve for x. 5x + 6x = 22 11x = 22 x = 22 \u00F7 11 x = 2 Next, plug x back into the second equation for y and solve. y = 2x y = 2 \u00D7 2 y = 4
