Question

pls give me answer to the question​

Answer 1

Step-by-step explanation:

Question 1

Let the present age of Renu's brother = x

then, the present age of Renu = 4x

Five years ago age of Renu’s brother = x - 5

Five years ago age of Renu = 9(x-5) = 9x - 45

ATQ

→ 4x - 5 = 9x - 45

→ 4x - 9x = -45 + 5

→ -5x = -40

→ x = -40/-5

→ x = 8

Therefore, Renu’s brother’s present age = 8years

and Renu’s present age = 4(x) = 4(8) = 32 years

Question 2

Let , the three consecutive integers = x , x+1 , x+2

ATQ

→ 2x + 3(x+1) + 4(x+2) = 56

→ 2x + 3x + 3 + 4x + 8 = 56

→ 9x + 11 = 56

→ 9x = 56 - 11

→ 9x = 45

→ x = 45/9

→ x = 5

Therefore , three integers are

• x = 5
• x + 1 = 5 + 1 = 6
• x + 2 = 5 + 2 = 7
