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 9b - 2b = -2b + 3x + 5 for b in terms of x.
| \(\frac{4}{13}\)x - \(\frac{6}{13}\) | |
| 9x - 8 | |
| \(\frac{5}{11}\)x + \(\frac{5}{11}\) | |
| -6x + 6 |
