Question

7(2m + 3) - 3( 5m -2) = 5(3m -4) - 3( 3m - 4)

Answer 1

7 (2m + 3) - 3 (5m - 2) = 5 (3m - 4) - 3 (3m - 4)

=> 14m + 21 - 15m + 6 = 15m - 20 - 9m + 12

=> 14m - 15m + 21 +6 = 15m - 9m -20 + 12

=> - m + 27 = 6m - 8

=> - m - 6m = - 8 - 27

=> - 7m = - 35

=> m = (- 35)/ (- 7)

=> m = 5 (Ans)
