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 - 9c = -6c + 4y + 3 for c in terms of y.
| -\(\frac{2}{3}\)y + 1\(\frac{1}{2}\) | |
| -\(\frac{4}{15}\)y + \(\frac{2}{5}\) | |
| -1\(\frac{1}{2}\)y + 2 | |
| 3\(\frac{1}{4}\)y + \(\frac{3}{4}\) |
