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 -4a - 2a = 7a + 3x - 4 for a in terms of x.
| -\(\frac{5}{11}\)x + \(\frac{4}{11}\) | |
| -\(\frac{5}{9}\)x + \(\frac{5}{9}\) | |
| -5x - \(\frac{2}{3}\) | |
| -2x + 2 |
