Explanation The given equation is x − 1 + x = 3 . Solve the equation as follows. x − 1 + x = 3 x − 1 = 3 − x ( x − 1 ) 2 = ( 3 − x ) 2 x − 1 = x 2 − 6 x + 9 On further simplification, x 2 − 7 x + 10 = 0 ( x − 5 ) ( x − 2 ) = 0 x − 5 = 0 or x − 2 = 0 x = 5 or x = 2 Therefore, the solution of equation is x = 5 or x = 2 . Verify the solution x = 5 by substituting x = 5 in x − 1 + x = 3
