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