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 2b - 4b = -6b + 9x - 9 for b in terms of x.
| -2\(\frac{1}{2}\)x - 4 | |
| -3\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) | |
| 3x - 2 | |
| 1\(\frac{5}{8}\)x - 1\(\frac{1}{8}\) |
