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 -6a + 3a = -3a + 7x + 3 for a in terms of x.
| -13x - 6 | |
| -1\(\frac{1}{3}\)x - 1 | |
| \(\frac{1}{2}\)x - \(\frac{5}{12}\) | |
| -\(\frac{1}{2}\)x + 1 |
