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