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 - 2a = 7a - 5x + 2 for a in terms of x.
| 2\(\frac{1}{2}\)x + 2 | |
| 1\(\frac{1}{2}\)x - 1 | |
| 1\(\frac{2}{3}\)x - \(\frac{7}{9}\) | |
| -2x - 6 |
