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