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