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 -7a + 3a = 5a - 2x + 3 for a in terms of x.
| 2\(\frac{2}{5}\)x + \(\frac{4}{5}\) | |
| \(\frac{3}{10}\)x - \(\frac{1}{10}\) | |
| \(\frac{5}{12}\)x - \(\frac{1}{4}\) | |
| 4x - 5 |
