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 - 5c = -c + 4z + 3 for c in terms of z.
| 9z + 3 | |
| -z - \(\frac{1}{4}\) | |
| 1\(\frac{4}{9}\)z + \(\frac{8}{9}\) | |
| \(\frac{5}{14}\)z - \(\frac{3}{7}\) |
