Question

please solve this question.
this is algebra equations so please show me the full method you can take the photo and send me in the answer section.
please solve this all three sums with the method

Answer 1

let Singh's age be x

and sunils age be x+5

therefore,

x+x+5=37

2x+5=37

2x=37-5

2x=32

x=32/2

x=16

Singh's Age is 16

sunils age is 21

Answer 2

(1)Sunil is 5 years More than Gurcharan

Let Gurcharan present Age=x years

Then Sunil Present Age=(x+5) years

Sum of Their ages=37

A/Q

x+(x+5)=37

x+x+5=36

2x+5=37

2x=37-5

2x=32

x=32/2

x=16

Age of Gurcharan =x=16 years

Age of Sunil=x+5=16+5=21 years

(2)Let Number=x

When it Increase by 6=4/3 of itself

A/q

$x + 6 = \frac{4}{3} x \\ \\ 6= \frac{4}{3} x - x \\ \\ 6= \frac{4x - 3x}{3} \\ \\ 6 = \frac{x}{3} \\ \\ x = 6 \times 3 \\ \\ x = 18$

Number=18

(3) Let Number=x

When 7 added to 2 times x=55

7+2x=55

2x=55-7

2x=48

x=48/2

x=24

Number=24
