\(a,x\times2+x\times8=960\)
\(x\times\left(2+8\right)=960\)
\(x\times10=960\)
\(x=960:10\)
\(x=96\)
\(b,x\times13-x\times4=612\)
\(x\times\left(13-4\right)=612\)
\(x\times9=612\)
\(x=612:9\)
\(x=68\)

x nhân 2 + x nhân 8 = 2470
\(x\times2+x\times8=2470\)
\(x\times\left(2+8\right)=2470\)
\(x\times10=2470\)
\(x=2470:10\)
\(x=247\)
nha bạn ^_^
\(x\times2+x\times8=2470\)
\(x\times\left(2+8\right)=2470\)
\(x\times10=2470\)
\(x=2470:10\)
\(x=247\)

15048:a - 2470:b thay a=32 va b=21 ta co
15048:32 - 2470:21=470,25 - 117,61
= 352,64

\(x.8=450.x+3\)
\(\left(450-8\right)x+3=0\)
\(442x=-3\)
x=\(-\frac{3}{442}\)


X x 2 + X x 8 = 2470
X x ( 2 + 8 ) = 2470
X x 10 = 2470
X = 2470 : 10
X = 247
X x 197 - X x 97 = 70600
X x ( 197 - 97 ) = 70600
X x 100 = 70600
X = 70600 : 100
X = 706
X x 2 + X x 8 = 2470
X x ( 2 + 8 ) = 2470
X x 10 = 2470
X = 2470 : 10
X = 247
X x 197 - X x 97 = 70600
X x ( 197 - 97 ) = 70600
X x 100 = 70600
X = 70600 : 100

X x 12 = 936 + X x 8
X x 12 - X x 8 = 936
X x ( 12 - 8 ) = 936
X x 4 = 936
X = 936 : 4
X = 234
Ta có:
X x 12 = 936 + X x 8
=> X x 12 - X x 8 = 936
=> X x 4 = 936
=> X = 936 : 4 = 234
Chúc bạn học tốt !!! ^^

1235×9–2470×2+1235×5
=1235×9–1235×2×2+1235×5
=1235×9–1235×4+1235×5
=1235×(9−4+5)
