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 -3b - 4b = -6b - 9x + 9 for b in terms of x.
| -2\(\frac{3}{5}\)x + \(\frac{2}{5}\) | |
| 12x - 9 | |
| \(\frac{2}{3}\)x - 2\(\frac{1}{3}\) | |
| -1\(\frac{2}{3}\)x + 3 |
