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