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 - 7c = -2c - 2z + 8 for c in terms of z.
| 4\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) | |
| \(\frac{6}{11}\)z + \(\frac{7}{11}\) | |
| \(\frac{5}{9}\)z + \(\frac{8}{9}\) | |
| 11z - 1 |
