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 8a - 5a = -5a - 6x + 9 for a in terms of x.
| -\(\frac{1}{16}\)x + \(\frac{3}{16}\) | |
| -\(\frac{9}{13}\)x + \(\frac{5}{13}\) | |
| x + 2\(\frac{2}{3}\) | |
| -\(\frac{1}{13}\)x + \(\frac{9}{13}\) |
