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