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 -3c + c = -4c - 4z + 7 for c in terms of z.
| -5z + 7 | |
| -\(\frac{4}{11}\)z - \(\frac{4}{11}\) | |
| 1\(\frac{2}{3}\)z + 2\(\frac{2}{3}\) | |
| -14z - 7 |
