Ответ:
They baked 54 brownies
Step-by-step explanation:
We have a total of b brownies
Then we threw away 24
b-24
Then we split them between the 3 siblings
(b-24)/3
Everyone got 10
(b-24)/3 =10
Solve for b
(b-24)/3 =10
Multiply by 3 on each side
(b-24)/3 *3 =10*3
b-24 = 30
Add 24 to each side
b-24+24 = 30+24
b = 54
