Question:

5x + 3y = 22

y = 2x

A
4

explanation

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
