Question

answer this following with explanation they get more points

Answer 1

(4x-3x)/12=14
x=14*12=168

Answer 2

(30)

⇒ x/3 - x/4 = 14

⇒ 4x - 3x = 14 * 12

⇒ x = 168.

Therefore, Option (B) is the answer.

(31)

Given : (x/2) - (1/4) = (x/3) + (1/2)

⇒ (x/2) = (x/3) + (1/2) + (1/4)

⇒ (x/2) = (x/3) + (3/4)

⇒ (x/2) - (x/3) = 3/4

⇒ (x/6) = (3/4)

⇒ x = (9/2)

⇒ x = 4 1/2.

Therefore, Option (C) is the right answer.

(32)

Given : (2 + x)/(2 - x) = 5/4

⇒ 4(2 + x) = 5(2 - x)

⇒ 8 + 4x = 10 - 5x

⇒ 4x = -5x + 2

⇒ 9x = 2

⇒ x = 2/9

Therefore, Option (A) is the correct answer.

(33)

Same as Question no 32 : Answer is Option (A).

(34)

Given : (x + 3)/(x + 5) =  (x - 2)/(x + 2)

⇒ (x + 3)(x + 2) = (x - 2)(x + 5)

⇒ x^2 + 5x + 6 = x^2 + 3x - 10

⇒ x^2 + 5x = x^2 + 3x - 16

⇒ 2x = -16

⇒ x = -8.

(35)

Same as Question (34) : Answer is Option (D)

(36)

Same as Question (34) : Answer is Option (B)

(37)

Given : (1/x) + (3/x) = 11/3

⇒ (3/x) + (9/x) = 11

⇒ 12/x = 11

⇒ 12 = 11x

⇒ x = 12/11

Therefore, Option (C) is the correct answer.

Hope this helps!
