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 4b - 5b = -7b - z - 4 for b in terms of z.
| 4z + 2 | |
| -\(\frac{7}{8}\)z + \(\frac{5}{8}\) | |
| 8z + 6 | |
| \(\frac{4}{11}\)z - \(\frac{4}{11}\) |
