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 -8c + 9c = -3c - 3y + 7 for c in terms of y.
| 2\(\frac{2}{5}\)y - 1\(\frac{2}{5}\) | |
| \(\frac{1}{4}\)y - \(\frac{3}{8}\) | |
| -\(\frac{2}{9}\)y - \(\frac{5}{9}\) | |
| 3y - \(\frac{1}{3}\) |
