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 + 4a = a - 2x - 3 for a in terms of x.
| -\(\frac{1}{3}\)x + \(\frac{1}{3}\) | |
| \(\frac{3}{4}\)x + \(\frac{3}{8}\) | |
| \(\frac{5}{13}\)x - \(\frac{6}{13}\) | |
| 10x - 7 |
