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 -7b - 6b = 3b + 3y + 1 for b in terms of y.
| -3\(\frac{1}{3}\)y - 2\(\frac{1}{3}\) | |
| -\(\frac{9}{10}\)y - \(\frac{1}{10}\) | |
| 5y + 8 | |
| -2y - 2 |
