\(\left(x-36\right):18=12\)
\(x-36=12.18\)
\(x-36=216\)
\(x=252\)
vậy \(x=252\)
\(5x-3=3x-11\)
\(5x-3x=-11+3\)
\(2x=-8\)
\(x=-4\)
vậy \(x=-4\)
\(3x+5x=16\)
\(8x=16\)
\(x=2\)
vậy \(x=2\)
\(2\left(x+1\right)=10\)
\(x+1=5\)
\(x=4\)
vậy \(x=4\)
k nha Pham Tuyet Nhung
1.=> x-36 = 216 = > x = 216 +36 =252
2. =>2x = -8 = > x= -4
3.8 x = 16 = > x = 2
4 . => x= 10 -1 = 9
ok có j ko hiểu hỏi riêng nha
( x - 36 ) : 18 = 12
x - 36 = 12 . 18
x - 36 = 216
x = 216 + 36
x = 252
5x - 3 = 3x - 11
5x - 3x = -11 + 3
2x = -8
x = -8 : 2
x = -4
3x + 5x = 16
8x = 16
x = 16 : 8
x = 2
2 ( x + 1 ) = 10
x + 1 = 10: 2
x + 1 = 5
x = 5-1
x = 4
( x - 36 ) : 18 = 12
<=> x - 36 = 12 . 18
<=> x - 36 = 216
<=> x = 216 + 36
<=> x = 252
5x - 3 = 3x - 11
<=> 5x - 3x = 3 + 11
<=> 2x = 14
<=> x = 14 : 2 = 7
3x + 5x = 16
<=> 8x = 16
<=> x = 16 : 8 = 2
2 ( x + 1 ) = 10
<=> x + 1 = 10 : 2
<=> x + 1 = 5
<=> x = 5 - 1 = 4
