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