Question

Solve the equation 3x-4y=16 for x

Answer 1

Hi there!

One little tip of advice I would like to give you is that when solving equations with 2 variables, and you're looking for only one, the second will always end up in your answer. So, since we're solving for x, the y will end up in our equation. :D

Let's begin!

`3x - 4y = 16`

Step 1) Add 4y to both sides.

`3x - 4y + 4y = 16 + 4y 3x = 4y + 16`

Step 2) Divide both sides by 3.

`(3x)/(3) = (4y + 16)/(3)`

`x = (4)/(3) y + (16)/(3)`

Final answer -

`x = (4)/(3) y + (16)/(3)`

If you wanted to see this graphed, however, see the attached file. :)

Hope this helps!
