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 - 7b = 2b - 9x - 4 for b in terms of x.
| \(\frac{2}{11}\)x + \(\frac{4}{11}\) | |
| x + 1\(\frac{1}{3}\) | |
| 1\(\frac{4}{7}\)x - 1 | |
| -1\(\frac{1}{2}\)x + \(\frac{2}{5}\) |
