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 - 5a = -5a + 7x - 2 for a in terms of x.
| -x + \(\frac{3}{7}\) | |
| -x + 1 | |
| 1\(\frac{1}{3}\)x - \(\frac{2}{9}\) | |
| 2\(\frac{1}{2}\)x - \(\frac{1}{2}\) |
