8x - 3x = 430
x( 8 - 3 ) = 430
5x = 430
x = 430 : 5
x = 86
\(a,x\times2+x\times8=960\)
\(x\times\left(2+8\right)=960\)
\(x\times10=960\)
\(x=960:10\)
\(x=96\)
\(b,x\times13-x\times4=612\)
\(x\times\left(13-4\right)=612\)
\(x\times9=612\)
\(x=612:9\)
\(x=68\)
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 ^_^
Vu truong haiĐúng, Đúng, Đúng\(x\times2+x\times8=2470\)
\(x\times\left(2+8\right)=2470\)
\(x\times10=2470\)
\(x=2470:10\)
\(x=247\)
1235×9–2470×2+1235×5
=1235×9–1235×2×2+1235×5
=1235×9–1235×4+1235×5
=1235×(9−4+5)
=1235×10
=12350
Thứ tự các số từ bé đến lớn là: 2469, 2470, 2476, 24670, 24675
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=\(-\frac{3}{442}\)
