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 + 9c = -7c - 8z + 6 for c in terms of z.
| -2z - \(\frac{4}{5}\) | |
| 17z - 6 | |
| \(\frac{4}{5}\)z + \(\frac{1}{5}\) | |
| \(\frac{8}{9}\)z - \(\frac{1}{3}\) |
