100 =2(30) + 2w
100 =60 + 2w

Answer:
9 students in music class.
Step-by-step explanation:
In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.
4 x _ = 12. —> 4 x 3 = 12.

For music there are 3.
so we multiply by 3 like we did with the 4.
3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.
