Question

Which is a possible way to rewrite the equation y=3x 3b solve for b?

Answer 1

3x-y/3=b, you are isolating b to the other side

Answer 2

we have

`y=3x+3b`

solve for b (clear variable b)

Adds -3x on both sides

`y-3x=3x+3b-3x\\ 3b=y-3x`

Divide by 3 on both sides

`(3b)/(3) =(y)/(3) -(3x)/(3) \\ \\ b=(y)/(3)-x`

therefore

the answer is

`b=(y)/(3)-x`
