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