Question

Malti is 3 years younger than her brother,Sanjay. If the sum of their ages is ages is 33 years, write an equation to find their ages......... The answer is 2x-3=3 but plz explain step-by-step with correct method ​

Answer 1

Step-by-step explanation:

Let the age of Malti be x and her brother Sanjay is y.

Malti is 3 years younger than sanjay,

x = y - 3. So, y-x=3

Sum of their ages is 33.

x + y = 33

Add both the equations,

y = 18

Substitute y value in any one of the equation, we get

x = 15

Answer 2

Answer:

Let age of her brother Sanjay = x

A.T.Q.

2x -3 = 33

2x = 33 +3

2 x = 36

x = 36÷2

x = 16

Hence, Maltis age = 16-3 = 13

Sanjay age = 16
