135-5.(x+4)=35
5.(x+4)=135-35
5.(x+4)=100
x+4=100:2
x+4=50
x=50-4
x=46
Vậy x=46
Bấm đúng cho mình nha
<=>135-5x-20=35
<=>115-5x=35
<=>5x=80
<=>x=16
ủng hộ nha:))
DỄ MÀ BẠN
135-5.(x+4)=35
5.(x+4)=135-35
5.(x+4)=100
(x+4)=100:5
x+4=20
x=20-4
x=16
135 - 5.(x + 4 ) = 35
=>135 - 5x +20 = 35
=>115 - 5x =35
=> 5x = 115 - 35 =75
=> x = 15
Tích đúng cho mình nha .Cảm ơn nhiều !!!
\(135-5\left(x+4\right)=35\)
\(5\left(x+4\right)=135-35\)
\(5.\left(x+4\right)=100\)
\(x+4=100:5\)
\(x+4=20\)
\(x=20-4\)
\(x=16\)
vậy x=16
135 - 5.(x + 4) = 35
5.(x + 4) = 135 - 35
5.(x + 4) = 100
x + 4 = 100 : 5
x + 4 = 20
x = 20 - 5
x = 15
135 - 5.(x + 4) = 35
5.(x + 4) = 135 - 35
5.(x + 4) = 100
x + 4 = 100 : 5
x + 4 = 20
x = 20 - 5
x = 15
