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 - 7c = -5c - 4y + 2 for c in terms of y.
| -\(\frac{3}{4}\)y - \(\frac{1}{2}\) | |
| -\(\frac{5}{11}\)y - \(\frac{3}{11}\) | |
| y - \(\frac{3}{4}\) | |
| -\(\frac{1}{4}\)y - \(\frac{1}{2}\) |
