When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve b - 5b = 6b - y - 7 for b in terms of y.
13y + 2 | |
\(\frac{1}{2}\)y - \(\frac{9}{14}\) | |
-\(\frac{4}{5}\)y + 1\(\frac{2}{5}\) | |
\(\frac{1}{4}\)y - \(\frac{1}{2}\) |
