Answer:

sorry I don't know the answer can u pls mark me as brainlist 2x+3x=8

Answer 2

Answer:

if we will draw the blue ball but the value of red balls will not change

let the ratio be of 2y:5y

2y = red ball = 8

so y= 8÷2 = 4

present blue balls = 5y = 5× 4

=20

one blue ball was removed

so , x= 5y +1

x=20+1

x=11
