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 8b - 7b = -b - 9x + 9 for b in terms of x.
| \(\frac{4}{9}\)x - \(\frac{2}{3}\) | |
| -\(\frac{3}{4}\)x - \(\frac{3}{4}\) | |
| x + 2 | |
| -\(\frac{2}{9}\)x + 1 |
