Answer 1

Answer:

black=45

white =55

Step-by-step explanation:

no of ball in box=100

no of black balls=x

no of white ball=x+10

x+x+10=100

2×+10=100

2x=100-10

2x=90

x=90/2

x=45

no of black balls =45

no of black balls =45+10=55

Answer 2

Given:-

Total balls in a box=100

Let the white balls=x

Black balls=10 more than white balls=x+10

so,

=>x+(x+10)=100

=>2x+10=100

=>2x=100-10

=>2x=90

=>x=90/2

=>x=45

White balls=x=45

Black balls=x+10=45+10=55
