(27-x)+(15+x)=x-24
=> 27- x + 15 + x -x + 24 = 0 (chuyển vế)
=> -x + 66 = 0
=> -x = -66
=> x =66
(27-x)+(15+x)=x-24
27-x+15+x=x-24
-x+x-x=-24-27-15
-x=-66
x=66
Vậy x=66
\(\left(27-x\right)+\left(15+x\right)=x-24\)
<=>\(27-x+15+x=x-24\)
<=>\(-x+x-x==24-15-27\)
<=>\(-x=-18\)
<=>\(x=18\)
(27-x)+(15+x)=x-24
<=> 27 - x +15 + x = x-24
<=> 42 = x - 24
<=> x= 42 + 24 = 66
\(\left(27-x\right)+\left(15+x\right)=x-24\)
\(\Leftrightarrow27-x+15+x=x-24\)
\(\Leftrightarrow27+15=x-24\)
\(\Leftrightarrow42=x-24\)
\(\Leftrightarrow x=24+42\)
\(\Leftrightarrow x=66\)
Vậy \(x=66\)
(27-x)+(15+x)=x-24
<=>27-x+15+x=x-24
<=>27-x+15+x-x+24=0
<=>66-x=0
<=>x=66
Vậy x=66
Trả lời:
(27 - x) + (15 + x) = x - 24
27 - x + 15 + x = x - 24
42 = x - 24
x = 42 + 24
x = 66
Vậy x = 66
Hok tốt!
