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 + 2b = -5b + 5y - 7 for b in terms of y.
| y - 1\(\frac{1}{3}\) | |
| -\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| \(\frac{1}{2}\)y - 1\(\frac{1}{6}\) | |
| \(\frac{1}{9}\)y - \(\frac{2}{3}\) |
