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 -8b - 2b = 9b + 4x + 9 for b in terms of x.
| -x - 3 | |
| -2\(\frac{1}{4}\)x + 2 | |
| \(\frac{3}{7}\)x - 1\(\frac{2}{7}\) | |
| -\(\frac{6}{17}\)x - \(\frac{9}{17}\) |
