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 - c = 7c + 9z + 5 for c in terms of z.
| -\(\frac{1}{3}\)z + \(\frac{2}{15}\) | |
| 10z + 5 | |
| 4\(\frac{1}{3}\)z - 3 | |
| 3\(\frac{1}{2}\)z + 3 |
