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 2a + 4a = 7a - 8x - 6 for a in terms of x.
| 2\(\frac{2}{5}\)x + 1\(\frac{1}{5}\) | |
| -1\(\frac{1}{3}\)x - 1\(\frac{2}{3}\) | |
| -1\(\frac{2}{3}\)x - 2\(\frac{1}{3}\) | |
| -\(\frac{2}{5}\)x + \(\frac{3}{10}\) |
