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 5a - 2a = 9a + 5x - 1 for a in terms of x.
| \(\frac{3}{8}\)x - \(\frac{1}{8}\) | |
| 2\(\frac{1}{3}\)x - 2\(\frac{2}{3}\) | |
| -1\(\frac{3}{4}\)x + \(\frac{1}{4}\) | |
| 1\(\frac{1}{7}\)x - 1\(\frac{2}{7}\) |
