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 5c - 8c = -c + y + 9 for c in terms of y.
| -\(\frac{6}{13}\)y - \(\frac{8}{13}\) | |
| -1\(\frac{3}{11}\)y - \(\frac{6}{11}\) | |
| 3\(\frac{1}{2}\)y + 4 | |
| 1\(\frac{1}{2}\)y + 1\(\frac{1}{2}\) |
