Combined with practical life experience, make up an application problem, so that the equation is 2x + 3 = 3x + 2

The teacher assigned me some homework, I did it for 2 hours, and there were 3 questions left. I did it for 3 hours, and there were 2 questions left. How many questions should I do every hour?

Given x ^ 2-5x + 25 = 0, find the value of x ^ 3

125

(x+5)(x^2-5x+25)

(x+5)(x²-5x+25)
=(x+5)(x-5)
=x²-5²

0.3(x+1)+0.25(100-x)=2/5x

The original equation can be taken as 3 (x + 1) / 10 + (100-x) / 4 = 2x / 5
Remove the denominator to get 6 (x + 1) + 5 (100-x) = 8x
Remove the brackets to get 6x + 6 + 500-5x = 8x
The result is 8x-x = 500 + 6
7x = 506
The coefficient of 1 is x = 506 / 7
