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 -6c + 9c = -2c + 6y - 7 for c in terms of y.
| 2y + \(\frac{1}{2}\) | |
| -\(\frac{5}{12}\)y + \(\frac{3}{4}\) | |
| \(\frac{3}{4}\)y + 1\(\frac{3}{4}\) | |
| \(\frac{1}{9}\)y - 1 |
