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 a + 8a = -4a - 9x + 5 for a in terms of x.
| 3\(\frac{4}{5}\)x - 1\(\frac{4}{5}\) | |
| -3\(\frac{2}{5}\)x + 1 | |
| -\(\frac{1}{16}\)x + \(\frac{1}{16}\) | |
| 1\(\frac{3}{13}\)x + \(\frac{5}{13}\) |
