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 5b + 8b = 7b - 6x + 7 for b in terms of x.
| \(\frac{2}{3}\)x - \(\frac{2}{3}\) | |
| -\(\frac{11}{14}\)x + \(\frac{1}{2}\) | |
| 2\(\frac{1}{4}\)x - 2\(\frac{1}{4}\) | |
| 7x - 3\(\frac{1}{2}\) |
