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 - 8a = 6a - 9x - 8 for a in terms of x.
| -\(\frac{1}{3}\)x - 2\(\frac{2}{3}\) | |
| \(\frac{1}{7}\)x - \(\frac{6}{7}\) | |
| -1\(\frac{1}{7}\)x - \(\frac{3}{7}\) | |
| -x + 1\(\frac{1}{5}\) |
