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 - 4a = 4a + 6x + 4 for a in terms of x.
| 10x + 4 | |
| 2\(\frac{1}{6}\)x - 1\(\frac{1}{6}\) | |
| -\(\frac{1}{17}\)x - \(\frac{6}{17}\) | |
| 4\(\frac{1}{4}\)x - \(\frac{1}{2}\) |
