A bag contains x yellow balls, 2x + 1 green balls and 3x + 2 black balls. There are 39 balls in the bag. Find the numbers of yellow, green and black balls in the bag

no. of yellow balls = x = 6

no. of green balls= 2x+1= 2×6+1= 13

no of black balls= 3x+2= 3×6+2= 20

Step-by-step explanation:

we can write it as

x+ 2x+1 + 3x+ 2 = 39

6x+3=39

6x=39-3

6x= 36

x= 36/6

x= 6

no. of yellow balls = x = 6

no. of green balls= 2x+1= 2×6+1= 13

no of black balls= 3x+2= 3×6+2= 20

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
