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 4a + 2a = 8a - 5x + 8 for a in terms of x.
| 1\(\frac{3}{4}\)x - 2 | |
| -\(\frac{4}{5}\)x + 1\(\frac{1}{5}\) | |
| \(\frac{2}{3}\)x - \(\frac{2}{3}\) | |
| \(\frac{6}{7}\)x + \(\frac{1}{7}\) |
