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