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 + 8b = 8b + 4x - 9 for b in terms of x.
| 1\(\frac{2}{11}\)x - \(\frac{7}{11}\) | |
| \(\frac{11}{15}\)x - \(\frac{1}{3}\) | |
| -4x - 9 | |
| 4\(\frac{2}{3}\)x + 2 |
