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 + 8b = -5b - 5z - 9 for b in terms of z.
| -1\(\frac{5}{8}\)z - 1\(\frac{1}{8}\) | |
| 1\(\frac{1}{4}\)z - \(\frac{3}{8}\) | |
| -\(\frac{1}{14}\)z - \(\frac{5}{14}\) | |
| -\(\frac{1}{9}\)z + \(\frac{8}{9}\) |
