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 = -5c - 8z + 6 for c in terms of z.
| -\(\frac{1}{9}\)z - \(\frac{2}{9}\) | |
| -2z + 1\(\frac{1}{7}\) | |
| -1\(\frac{4}{13}\)z + \(\frac{6}{13}\) | |
| -3z - 8 |
