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 + 3c = 6c - 9y - 9 for c in terms of y.
| 1\(\frac{1}{4}\)y - \(\frac{3}{8}\) | |
| 3\(\frac{3}{4}\)y + \(\frac{3}{4}\) | |
| -2\(\frac{3}{5}\)y - 1 | |
| 1\(\frac{1}{11}\)y + \(\frac{9}{11}\) |
