Question

tìm x lớp 7: ( 2x-3)-(x-5)=(x+2) - (x-1)

Answer 1

\(\left(2x-3\right)-\left(x-5\right)=\left(x+2\right)-\left(x-1\right)\Leftrightarrow2x-3-x-5=x+2-x+1\Leftrightarrow x-8=3\Leftrightarrow x=3+8=11\)

Answer 2

`(2x - 3) - (x - 5) = (x + 2) - (x - 1)`

`<=> 2x - 3 - x - 5 = x+2 - x + 1`

`<=> x - 8 = 3`

`<=> x = 11`

Vậy `x = 11`
