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 + 9c = -7c - 6x - 9 for c in terms of x.
| 3x + \(\frac{1}{4}\) | |
| \(\frac{1}{6}\)x + 1\(\frac{1}{6}\) | |
| x + \(\frac{2}{3}\) | |
| -2\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) |
