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 -3c + 9c = 9c - 8y - 5 for c in terms of y.
| 1\(\frac{5}{12}\)y + \(\frac{5}{12}\) | |
| y + 1 | |
| 4y + 2 | |
| -1\(\frac{3}{11}\)y - \(\frac{7}{11}\) |
