Solve for x: 6x – 8y = 12

Tcecarenko [31]

Hi there!

Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.

$6x + 8y = 12$

Step 1) Add 8y to both sides.

$6x - 8y + 8y = 12 + 8y 6x = 8y + 12$

Step 2) Divide both sides by 6.

$\frac{6x}{6} = \frac{8y + 12}{6}$

$x = \frac{4}{3} y + 2$

Final Answer -

$x = \frac{4}{3} y + 2$

Hope this helps! :D
