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