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 4c - c = -2c + 5y + 9 for c in terms of y.
| -\(\frac{7}{15}\)y + \(\frac{3}{5}\) | |
| y + 1\(\frac{1}{2}\) | |
| y - 7 | |
| -12y + 1 |
