x-1-2-3-4=0
x-(1+2+3+4)=0
x-10=0
x=0+10
x=10
vậy x=10
Trl :
x- 1 -2 -3 - 4 = 0
x = 0 + 4 + 3 + 2 + 1
x = 10
x - 1 - 2 - 3 - 4 = 0
x = 0+4+3+2+1
x = 10
x- 1 -2 -3 - 4 = 0
x=0+4+3+2+1
x=10
\(x-1-2-3-4=0\)
\(x-1-2-3=0 +4\)
\(x-1-2-3=4\)
\(x-1-2=4+3\)
\(x-1-2=7\)
\(x-1=7+2\)
\(x-1=9\)
\(x=9+1\)
\(x=10\)
x-1-2-3-4=0
\(\Leftrightarrow\)x-1-2=4+0
\(\Leftrightarrow\)x-1=4+2
\(\Leftrightarrow\)x=6+1
\(\Leftrightarrow\)x=7
Tim x:
x - 1 - 2 - 3 - 4 = 0
x = 0 + 3 + 2 + 1
x = 6
Ta có: x-1-2-3-4=0
=> x= 0+1+2+3+4
=> x= 8
cho mình nha nếu ko phiền
mình nhầm nha, kết quả bằng 10
Sai het mik lam lai ne ! Neu thay dung nho cho mik nha !
x - 1 - 2 -3 - 4 = 0
x = 0 + 4 + 3 + 2 + 1
x = 10
x-1-2-3-4=0
x =0+1+2+3+4
x x=10
vậy x=10
