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 -8c + c = -5c - 3z + 9 for c in terms of z.
| \(\frac{6}{13}\)z - \(\frac{3}{13}\) | |
| -9z - 7 | |
| -\(\frac{5}{13}\)z - \(\frac{5}{13}\) | |
| 1\(\frac{1}{3}\)z - 3 |
