Question

Amina think If a number and subtracts 5/2 from it. She multiply the result by 8 the result Now obtained is 3 times the same number she thought of. What is the number.​

Answer 1

$\huge\mathfrak\red{Answer :) }$

Let the number be x

• ⟹ (x-5/2) × 8=3x
• ⟹ 2x-5/2×8=3x
• ⟹ 4(2x-5)= 3x
• ⟹ 8x-20=3x
• ⟹ 8x-3x=20
• ⟹ 5x=20
• ⟹ x=20/5=4

Number = 4

Answer 2

Answer:

Let the number be x

⟹ (x-5/2) × 8=3x

⟹ 2x-5/2×8=3x

⟹ 4(2x-5)= 3x

⟹ 8x-20=3x

⟹ 8x-3x=20

⟹ 5x=20

⟹ x=20/5=4

Number = 4
