Question

please tell me in step by step​

Answer 1

Answer:

∴ x = 14

Step-by-step explanation:

x/4 + x/6 = x-7

or, x×3/4×3 + x×2/6×2 = x-7

or, 3x/12 + 2x/12 = x-7

or, (3x+2x) / 12 = x-7

or, 5x = (x-7)12

or, 5x = 12x - 84

or, 0= 12x - 5x - 84

or, 0 + 84 = 6x

or, 6x = 84

or. x = 84/6

∴ x = 14
