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 8b + 7b = -5b - 4z - 4 for b in terms of z.
| -z - \(\frac{7}{11}\) | |
| -\(\frac{11}{13}\)z - \(\frac{4}{13}\) | |
| -\(\frac{5}{8}\)z - \(\frac{5}{8}\) | |
| -z + \(\frac{1}{2}\) |
