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
