Question

Ma gandesc la un numar.adaug 2600 apoi 2400 din rezultat scad 4300 si obtin 3700.la ce numar m-am gandit?

Answer 1

x+2600+2400-4300=3700

x+2600+2400=3700+4300

x+2600+2400=8000

x+2600=8000-2400

x+2600=5600

x=5600-2600

x=3000

Answer 2

(x+2600+2400)-4300=3700
3700+4300=x+2600+2400
×+2600+2400=8000
8000-5000=×
x=3000
(3000+2600+2400)-4300=3700
