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 -9b - 2b = 2b + 9x + 9 for b in terms of x.
| -x - \(\frac{9}{11}\) | |
| x - \(\frac{2}{15}\) | |
| 3\(\frac{3}{4}\)x + 1\(\frac{3}{4}\) | |
| -\(\frac{3}{5}\)x + \(\frac{3}{5}\) |
