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 = -5c - 9y - 7 for c in terms of y.
| \(\frac{5}{12}\)y - \(\frac{3}{4}\) | |
| -1\(\frac{1}{2}\)y + 3 | |
| -\(\frac{3}{5}\)y - \(\frac{7}{10}\) | |
| -4y + \(\frac{3}{4}\) |
