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