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 -4c - c = -7c + 9z - 3 for c in terms of z.
| \(\frac{1}{2}\)z - \(\frac{3}{10}\) | |
| 3\(\frac{1}{3}\)z - 1 | |
| z + \(\frac{5}{8}\) | |
| 7z - 8 |
