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 7c + c = 8c + 4y + 8 for c in terms of y.
| -6y - 1 | |
| 3\(\frac{2}{5}\)y + \(\frac{3}{5}\) | |
| -3y - \(\frac{1}{2}\) | |
| -3y - 8 |
