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 + 5a = 6a - 6x + 4 for a in terms of x.
| -\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| \(\frac{11}{15}\)x - \(\frac{4}{15}\) | |
| 1\(\frac{2}{3}\)x - \(\frac{5}{6}\) | |
| -\(\frac{1}{2}\)x + \(\frac{9}{10}\) |
