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 + 8a = 4a - x + 5 for a in terms of x.
| 1\(\frac{1}{9}\)x - \(\frac{1}{9}\) | |
| 1\(\frac{2}{7}\)x - \(\frac{5}{7}\) | |
| -\(\frac{1}{11}\)x + \(\frac{9}{11}\) | |
| \(\frac{1}{2}\)x + \(\frac{3}{8}\) |
