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