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 + 9c = -9c + 9z + 8 for c in terms of z.
| 1\(\frac{1}{5}\)z + 1\(\frac{3}{5}\) | |
| z + 1\(\frac{3}{5}\) | |
| z + \(\frac{1}{5}\) | |
| -\(\frac{3}{11}\)z - \(\frac{4}{11}\) |
