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