Question

x=4 is the root of 12 x +8. = 56​

Answer 1

Answer:

x=4

12 x +8. = 56

12×4 + 8 = 56

48 + 8 = 56

56 = 56

hence proved , x = 4 is the root of 12 x +8. = 56

Answer 2

Answer:

   x = 4

-> 12x + 8 = 56

-> 12(4) + 8 = 56

-> 48 + 8 = 56

-> 56= 56

Hence proved, x = 4 is the root of 12x+8 = 56
