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 6c + 3c = 8c - 7y - 4 for c in terms of y.
| -\(\frac{3}{11}\)y - \(\frac{2}{11}\) | |
| 5y + 2 | |
| -1\(\frac{2}{3}\)y + \(\frac{1}{3}\) | |
| -y + 8 |
