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