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 - 8 for c in terms of z.
| 1\(\frac{3}{4}\)z + 1\(\frac{3}{4}\) | |
| 3\(\frac{1}{3}\)z + 2 | |
| -5\(\frac{2}{3}\)z - 2\(\frac{2}{3}\) | |
| -11z + 4 |
