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 -c - 3c = -7c - y + 6 for c in terms of y.
| -\(\frac{2}{3}\)y - \(\frac{1}{3}\) | |
| \(\frac{1}{3}\)y + 1 | |
| 3\(\frac{1}{2}\)y - 2 | |
| 7\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) |
