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