Alright, lets get started.
Suppose total number of dancers in school = x
We have given in question, 42 % of total dancers are ballet dancers.
So, we could find number of ballet dancers by finding 42 % of total dancers.
Number of ballet dancers = x * 42 %
Number of ballet dancers = x * 42/100 = 0.42 x
As per given in question, there are 63 ballet dancers in school.
Which means 0.42 x = 63
Dividing 0.42 from both sides
0.42 x / 0.42 = 63 / 0.42
x = 150
Hence number of total dancers in school = 150 : Answer

Answer:
x= -4, 6
Step-by-step explanation:
6x^2-12x=144
(6x^2-12x=144)/6
x^2-2x=24
(x+4)(x-6)=0
x+4=0 (x-6)=0
x=-4 x=6
