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 = -4c + 9z + 5 for c in terms of z.
| -7\(\frac{1}{2}\)z + \(\frac{1}{2}\) | |
| z + \(\frac{3}{4}\) | |
| 17z + 5 | |
| 10z + 3 |
