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 -2b + 7b = 9b + 7x - 4 for b in terms of x.
| \(\frac{1}{13}\)x + \(\frac{8}{13}\) | |
| 3\(\frac{1}{2}\)x - 1 | |
| -x - 4\(\frac{1}{2}\) | |
| x + \(\frac{4}{11}\) |
