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 4b - 6b = -b + 2x + 9 for b in terms of x.
| \(\frac{3}{4}\)x - 2 | |
| x + \(\frac{1}{5}\) | |
| 1\(\frac{3}{5}\)x + 1\(\frac{4}{5}\) | |
| -1\(\frac{4}{13}\)x + \(\frac{6}{13}\) |
