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 + 9b = -7b - 2x + 8 for b in terms of x.
| -\(\frac{5}{12}\)x - \(\frac{2}{3}\) | |
| -1\(\frac{1}{6}\)x - \(\frac{1}{3}\) | |
| x + 2\(\frac{1}{3}\) | |
| -3\(\frac{2}{3}\)x + 2\(\frac{2}{3}\) |
