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 = -2a + x + 3 for a in terms of x.
| -\(\frac{7}{8}\)x + \(\frac{3}{8}\) | |
| 2\(\frac{1}{5}\)x - \(\frac{3}{5}\) | |
| x + \(\frac{1}{2}\) | |
| \(\frac{3}{10}\)x - \(\frac{7}{10}\) |
