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 6c - c = 7c - 7z - 8 for c in terms of z.
| \(\frac{5}{14}\)z + \(\frac{1}{14}\) | |
| 6z + 8 | |
| -1\(\frac{4}{5}\)z + \(\frac{1}{5}\) | |
| \(\frac{3}{7}\)z + \(\frac{5}{7}\) |
