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 = -4b - z - 5 for b in terms of z.
| -z - \(\frac{1}{4}\) | |
| \(\frac{4}{11}\)z - \(\frac{5}{11}\) | |
| \(\frac{1}{2}\)z + \(\frac{1}{4}\) | |
| 1\(\frac{1}{3}\)z + \(\frac{8}{9}\) |
