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