Question

(x-7) : (x+7) = 3:17 solve this question​

Answer 1

Answer:

(x - 7) : (x+7) = 3: 17

(x-7) × 17 = 3 × (x+7)

17x - 119 = 3x + 21

17x - 3x = 21 + 119

14x = 140

x = 10

________________________________

(x - 7) : (x + 7) = 3 : 17

⟹ (x - 7) / (x + 7) = 3/17

⟹ (x - 7) × 17 = (x + 7) × 3

⟹ 17x - 119 = 3x + 21

⟹ 17x - 3x = 21 + 119

⟹ 14x = 140

⟹ x = 140/14

⟹ x = 10

value of x is 10
