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 9c + 9c = -4c - 3y + 2 for c in terms of y.
| -\(\frac{9}{10}\)y + \(\frac{2}{5}\) | |
| 13y - 3 | |
| -\(\frac{12}{13}\)y + \(\frac{2}{13}\) | |
| 9y + 1 |
