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 -2c - 4c = 8c - 8y - 2 for c in terms of y.
| \(\frac{4}{7}\)y + 1\(\frac{1}{7}\) | |
| -13y + 4 | |
| \(\frac{2}{5}\)y + \(\frac{1}{5}\) | |
| 3y + 5 |
