x : 5 + 1 +3 + 5 = 135
=> x : 5 + 9 = 135
=> x : 5 = 135 - 9
=> x :5 = 126
=> x = 126 x 5
=> x= 630
\(x:5+1+3+5=135\)
\(x:5=135-\left(1+3+5\right)\)
\(x:5=135-9\)
\(x:5=135-9\)
\(x:5=126\)
\(x=126.5\)
\(x=630\)
Hok giỏi nha!!!!!!!!!
x : 5 + 1 + 3 + 5 = 135
x : 14 = 135
x = 135 x 14
x = 1890
giá trị của x là 1890
x : 5 = 135 - 1 - 3 - 5
x : 5 = 126
x = 126 x 5
x = 630
\(x:5+1+3+5=135\)
\(x:5=135-\left(1+3+5\right)\)
\(x:5=135-9\)
\(x:5=126\)
\(x=126\times5\)
\(x=630\)
x:5+1+3=135-5
x:5+1+3=130
x:5+1=130-1
x:5+1=129
x:5=129-1
x:5=128
x=128*5
x=640
X:5 + 1+3+5=135
X:5 =135-1-3-5
X:5 =126
X =126x5
X =630
X:5+1+3+5=135
X:5+(1+3+5)=135
X:5+9 =135
