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 8a - 5a = 2a + 4x + 8 for a in terms of x.
| 1\(\frac{1}{6}\)x + \(\frac{1}{6}\) | |
| -9x - 4 | |
| 1\(\frac{1}{2}\)x + 1\(\frac{1}{3}\) | |
| 4x - 4\(\frac{1}{2}\) |
