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 + 5c = -5c + y - 7 for c in terms of y.
| -14y + 5 | |
| -\(\frac{2}{5}\)y - \(\frac{7}{10}\) | |
| \(\frac{5}{12}\)y + \(\frac{3}{4}\) | |
| -2y + 5 |
