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 -a - 2a = -2a + 3x + 2 for a in terms of x.
| 2x + 3 | |
| 5x + 2 | |
| -1\(\frac{1}{4}\)x - 2 | |
| -1\(\frac{5}{7}\)x + \(\frac{5}{7}\) |
