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 - a = -2a + 7x - 2 for a in terms of x.
| 5x - 6 | |
| -4x + 1 | |
| -1\(\frac{2}{5}\)x - 1\(\frac{3}{5}\) | |
| -\(\frac{3}{7}\)x + \(\frac{4}{7}\) |
