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 -5c + c = 4c + 2z + 7 for c in terms of z.
| -\(\frac{9}{14}\)z - \(\frac{2}{7}\) | |
| -1\(\frac{4}{7}\)z - \(\frac{5}{7}\) | |
| 1\(\frac{6}{13}\)z + \(\frac{8}{13}\) | |
| -\(\frac{1}{9}\)z - \(\frac{7}{9}\) |
