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 - 7c = 8c + 8z - 8 for c in terms of z.
| -\(\frac{6}{7}\)z + \(\frac{3}{7}\) | |
| -1\(\frac{4}{9}\)z + \(\frac{1}{3}\) | |
| -\(\frac{2}{7}\)z - \(\frac{4}{7}\) | |
| -3\(\frac{3}{4}\)z + 2 |
