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 = 6b + 9x + 5 for b in terms of x.
| -x + 1 | |
| -\(\frac{11}{15}\)x - \(\frac{1}{3}\) | |
| \(\frac{2}{7}\)x - 1\(\frac{1}{7}\) | |
| 12x + 9 |
