trả lời giúp mik với mik đang giải violympic (nhanh giúp mik nha)
x-(-25-17-2x)=6+x
=>x+25+17+2x=6+x
=>3x+42=6+x
=>3x-x=6-42
=>2x=-36
=>x=-18
x-(-25-17-2x)=6+x
X -( - 25 - 17 - 2x )= 6+x
X + 25 + 17 + 2x = 6 + x
X + 2x - x = - 25 - 17 + 6
2x = - 25 - 17 + 6
2x = - 36
X = - 36 : 2
X = - 18
x + 25 + 17 + 2x= 6 + x
3x + 42 = 6 + x
x - 3x = 42 - 6
-2x = 36
x = 36 :(-2)
x= -18
x-(-25-17-2x)=6+x
=>x-(-42-2x)=6+x
=>x+42+2x=6+x
=>42+2x=6
=>2x=-36
=>x=-18
x-(-25-17-2x)6+x vay x = ?
tìm x biết x-(-25-17-2x)=6+x
x - (-25 - 17 - 2x) = 6 + x
=> x + 25 + 17 + 2x = 6 + x
=> x + 2x - x = 6 - 25 - 7
=> 2x = -36
=> x = -36:2
=> x = -18
Chắc chắn là -18
Tick mình đi, mình tick lại cho!
x - ( -25 - 17 - 2x ) = 6 + x
x-(-25-17-2x)=6+x
x+25+17+2x-x=6
(x+2x-x)+(25+17)=6
2x+42=6
2x=6-42=-36
x=(-36):2=-18
Tim x biet
x-(-25-17-2x)=6+x
45-/-27-(-25)-x/=7+27
