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 8c + 7c = -4c + 8y - 6 for c in terms of y.
| 2\(\frac{1}{2}\)y - 3\(\frac{1}{2}\) | |
| y - 5 | |
| -4\(\frac{2}{3}\)y + 3 | |
| \(\frac{1}{12}\)y - \(\frac{1}{2}\) |
