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 3a - 5a = 2a - 5x - 3 for a in terms of x.
| -\(\frac{3}{13}\)x + \(\frac{9}{13}\) | |
| -2\(\frac{1}{2}\)x + \(\frac{3}{4}\) | |
| 4x + 1 | |
| x - 3 |
