answer me linear equations questions​

Answer 1

Step-by-step explanation:

age of gabreela=x

age of her brother=x+8 years

age of her sister =x-12

therefore;

it is given that total age =50 years

x+x+8+x-12=50

x+x+8+x=50+12

3x=50+12-8

3x=54

x=54/3

x=18

now...

age of gabreelia=x=18

age of her brother=x+18=18+8=26

and age of her sister=x-12=18-12=6
