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 -4c - 2c = 7c - 4z + 5 for c in terms of z.
| 2z - \(\frac{1}{2}\) | |
| -9z - 7 | |
| -1\(\frac{4}{7}\)z + \(\frac{1}{7}\) | |
| \(\frac{2}{11}\)z - \(\frac{5}{11}\) |
