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 - 7c = -2c - 6y + 8 for c in terms of y.
| -13y + 8 | |
| 2\(\frac{2}{5}\)y + \(\frac{1}{5}\) | |
| -\(\frac{1}{3}\)y - 2\(\frac{2}{3}\) | |
| -1\(\frac{5}{6}\)y + \(\frac{1}{3}\) |
