The correct equation is solved in option
Explanation of Solution
Given information:
The solution of equation in single variable.
Calculation:
Consider the of equations,
The above equation is wrong since when
The second last step is not defined. 7 should not be divided
The equation is solved wrong since when number jumps the equal to sign its sign changes.
The steps are all correct.
Thus, the correct equation is solved in option
