4x+8y=17<br> Solve for y
olasank [31]

Answer:

4x + 8y = 17  

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8

Then simplify the fractions to get:

y = -2x/4 + 17/8
