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 + 2b = 5b - 9x + 9 for b in terms of x.
| 1\(\frac{2}{9}\)x - 1 | |
| -\(\frac{3}{4}\)x - 1\(\frac{3}{4}\) | |
| -\(\frac{5}{7}\)x + 1 | |
| x + 2\(\frac{2}{3}\) |
