​

Answer 1

Answer:

Sheena age is 28 and her brother age is 20

Step-by-step explanation:

let x be the be Sheena brother age and x+8 be her age

then by question

x+8+x =48

=2x+8=48

=2x=48-8=40

x=40/2=20

therefore x = 20

then Sheena brother age=20 and Sheena age = x+8=20+8=28

Answer 2

✰ Given :-

Sheena is 8yrs younger than her brother Sippu

Sum of their ages is 48 years

$\:$

✰ To Find :-

Their ages

$\:$

✰ Solution :-

Let,

Sheena age be x-8

Her brother Sippu's age is x

Sum of their ages are 48yrs

So,

$⟹ \: \bf Sheena's \: age + Sippu's \: age = 48yrs$

$\bf⟹ \: x + x - 8 = 48$

$\bf⟹ \: 2x - 8 = 48$

$\bf⟹ \: 2 x = 48 + 8$

$\bf⟹ \: 2 x = 56$

$\displaystyle ⟹ \: \bf \: x = \cancel\frac{56}{2} = 28$

$\bf⟹ \: \large\boxed{ \colorbox{yellow}{ \bf x = 28}}$

∴ Sheena's age = x-8 = 28-8=20yrs

∴ Her brother Sippu's age = x = 28yrs

$\:$

✰ Proof :-

$\bf⟹ \: 28 + 20 = 48$

$\bf⟹ \: 48 = 48$

∵ Hence, verified ツ
