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 + 4a = -3a + 3x + 7 for a in terms of x.
| \(\frac{1}{2}\)x - 3\(\frac{1}{2}\) | |
| 12x + 7 | |
| -\(\frac{3}{10}\)x + \(\frac{9}{10}\) | |
| -\(\frac{5}{6}\)x + \(\frac{5}{6}\) |
