A box contains orange balls and green balls. The number of green balls is nine more than two times the number of orange balls. If there are 54 balls altogether, then how many green balls and how many orange balls are there in the box? There are orange balls and green balls in the box.

15 orange balls and 39 green balls

Step-by-step explanation:

Orange balls = x

Green balls = 2x + 9

2x + 9 + x = 54

3x + 9 = 54

3x = 45

x = 15

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
