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 + 8b = -9b + 3x - 8 for b in terms of x.
| -4x + 2 | |
| -x - 1\(\frac{3}{5}\) | |
| \(\frac{3}{10}\)x + \(\frac{1}{10}\) | |
| 1\(\frac{1}{10}\)x - \(\frac{9}{10}\) |
