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 2c - 8c = 3c + 5z - 9 for c in terms of z.
| -13z + 9 | |
| -9z - 7 | |
| -1\(\frac{1}{2}\)z + 1\(\frac{1}{6}\) | |
| \(\frac{3}{11}\)z - \(\frac{1}{11}\) |
