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 -3b + 2b = 7b + 9y + 2 for b in terms of y.
| -\(\frac{2}{3}\)y + 1\(\frac{1}{3}\) | |
| 1\(\frac{1}{6}\)y - \(\frac{1}{3}\) | |
| -\(\frac{7}{10}\)y - \(\frac{1}{5}\) | |
| y + 3 |
