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 9a + 2a = -3a - 3x + 5 for a in terms of x.
| \(\frac{1}{12}\)x - \(\frac{1}{12}\) | |
| -3\(\frac{1}{3}\)x - \(\frac{2}{3}\) | |
| -\(\frac{5}{12}\)x + \(\frac{5}{12}\) | |
| -\(\frac{5}{14}\)x + \(\frac{1}{2}\) |
