Answer» ve QUESTION can be WRITTEN as, = 3 × [(2m + 5)/ 3] = 3 × (3M -10) … [Multiplying both side by 3]= (2m + 5) = 9M – 30Transposing 2m to RHS and it becomes -2m and -30 to LHS it becomes 30= 30 + 5 = 9m -2m= 35 = 7mMultiplying both side by (1/7),= 7m × (1/7) = 35 × (1/7)= m = (35/7)= m = 5By substituting 5 in the place of m in given equation, we getLHS,= 2m + 5= 2 × (5) + 5= 10 + 5= 15RHS,= 9m – 30= 9 × (5) – 30= 45 – 30= 15By comparing LHS and RHS= 15 = 15∴ LHS = RHSHence, the result is verified. |
