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 = -5c + 9x - 1 for c in terms of x.
| 3x + 2\(\frac{2}{3}\) | |
| x - 5 | |
| 5\(\frac{2}{3}\)x - \(\frac{1}{3}\) | |
| -\(\frac{3}{14}\)x + \(\frac{5}{14}\) |
