It's simple you did not asked to solve this problem, but the equation for this is x+y = 425 X is the distance traveled on the first day, and Y is the distance traveled on the second day
X+y=425. This is as simple it can be, unless theres more information. x is the distance traveled on the first day and y is the distance traveled on the second day.
We take each number as x = 2x 3x 4x (2x)³+(3x)³+(4x)³=33957 8x³+27x³+64x³=33957 99x³=33957 x³=33957÷99 =∛343 x=7 2x=2×7=14 3x=3×7=21 4x=4×7=28 =the three numbers are 14,21,28
