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