Question

Solve this formula for y
4x+2y=8
y=

Answer 1

4x + 2y = 8
subtract 4x from both sides
2y=8-4x
divide both sides by 2 to isolate y
y=4-2x
the answer is y=4-2x

Answer 2

y = -2x + 4

Explanation:

`4x+2y=8\qquad\text{subtract 4x from both sides}\\\\4x-4x+2y=-4x+8\\\\2y=-4x+8\quad\text{divide both sides by 2}\\\\(2y)/(2)=(-4x)/(2)+(8)/(2)\\\\y=-2x+4`
