Which is a possible way to rewrite the equation y=3x 3b solve for b?
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
\(\frac{3b}{3} =\frac{y}{3} -\frac{3x}{3} \\ \\ b=\frac{y}{3}-x\)
therefore
the answer is
\(b=\frac{y}{3}-x\)
