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 6b + 7b = 7b - 9x + 4 for b in terms of x.
| x + 1\(\frac{1}{4}\) | |
| \(\frac{6}{11}\)x + \(\frac{8}{11}\) | |
| \(\frac{1}{14}\)x - \(\frac{3}{14}\) | |
| 16x - 4 |
