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 - 6c = c + 5z + 7 for c in terms of z.
| -z - 1 | |
| 3\(\frac{1}{2}\)z + 1 | |
| -\(\frac{2}{11}\)z - \(\frac{9}{11}\) | |
| -1\(\frac{5}{6}\)z - 1\(\frac{1}{6}\) |
