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 3b - 9b = 5b + 3x - 8 for b in terms of x.
| -6x + 4 | |
| -1\(\frac{1}{9}\)x + \(\frac{5}{9}\) | |
| 2\(\frac{1}{3}\)x - \(\frac{1}{2}\) | |
| 1\(\frac{6}{7}\)x - 1\(\frac{1}{7}\) |
