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