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 - 3c = -8c + 2y - 1 for c in terms of y.
| -2y + \(\frac{1}{3}\) | |
| -1\(\frac{1}{2}\)y - \(\frac{7}{10}\) | |
| \(\frac{5}{6}\)y - \(\frac{1}{6}\) | |
| -3y - 2\(\frac{2}{3}\) |
