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 -3a + 6a = 8a - 5x + 2 for a in terms of x.
| 2\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| -\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| -1\(\frac{1}{3}\)x - 2\(\frac{1}{3}\) | |
| x - \(\frac{2}{11}\) |
