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