Question

tìm x,biết:

(2x-3)-(x+2)=(x-2)-3(x-5)

Answer 1

(2x - 3) - (x + 2) = (x - 2) - 3(x - 5)

2x - 3 - x - 2 = x - 2 - 3x + 15

(2x - x) + (-3 - 2) = (x - 3x) + (-2 + 15)

x - 5 = -2x + 13

x + 2x = 13 + 5

3x = 18 

x = 6

Answer 2

(2x-3)-(x+2)=(x-2)-3(x-5)

2x-3-x-2=x-2-3x+3x5

x-5=-2x-2+15

x-5=-2x+13

x-(-2x)=5+13

x+2x=18

3x=18

x=6

Vậy x=6
