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