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 5c + 10c = -5c - 9y + 2 for c in terms of y.
| -y + \(\frac{5}{13}\) | |
| -1\(\frac{9}{10}\)y + \(\frac{1}{5}\) | |
| -1\(\frac{2}{3}\)y - \(\frac{1}{6}\) | |
| y - \(\frac{1}{4}\) |
