7 i hope this helps pls mark me the brainiest

Step-by-step explanation:

7 x 2 = 14

because if he's sister is 7 then suman is 7 years older that means 7 plus 7 because that equals 21

Answer 2

answer-let the age of suman's sister be x

so,the suman's age be x+7.

2x+7=21

2x=21-7

2x=14

x=14/2

x=7
