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 3c + 6c = c - 9y + 2 for c in terms of y.
| -7\(\frac{1}{2}\)y + 1 | |
| y + 1\(\frac{3}{5}\) | |
| 5y - \(\frac{1}{2}\) | |
| \(\frac{3}{10}\)y + \(\frac{7}{10}\) |
