3072 - X : 3 = 1564
X : 3 = 3072 - 1564
X : 3 = 1508
X = 1508 nhân 3
X = 4524

3072-x:3= 1564
x:3= 3072-1564
x:3= 1508
x = 1508 x 3
x = 4524
3072-x:3=1564
x:3=3072-1564
x:3=1508
x=1508x3
x=4524
P/s tham khảo nha

3072 * x : 3 = 64
3072 * x = 64 * 3
3072 * x = 192
x = 192 : 3072
x = 0,0625.
Vậy x = 0,0625.

a. x ÷ 24 = 35736
x = 35736 × 24
x = 857664
b. 43 × 95 + 43 × 4 + 43
= 43 × ( 95 + 4 + 1)
= 43 × 100
= 4300

Câu 10:
\(a,y\times7+y\times3=70\\ \Rightarrow y\times\left(7+3\right)=70\\ \Rightarrow y\times10=70\\ \Rightarrow y=7\\ b,18:y+12:y=3\\ \Rightarrow\left(18+12\right):y=3\\ \Rightarrow30:y=3\\ \Rightarrow y=10\)
câu 11:
\(a,9\times365+2\times365-365=\left(9+2-1\right)\times365=10\times365=3650\\ b,108:9-18:9=\left(108-18\right):9=90:9=10\\ c,43\times95+4\times43+43=43\times\left(95+4+1\right)=43\times100=4300\)
`3072 - x : 43 = 1564`
`x : 43 = 3072 - 1564`
`x : 43 = 1508`
`x=1508 xx 43`
`x=64844`
\(3072-x:43=1564\)
\(x:43=3072-1564\)
\(x:43=1508\)
\(x=43\times1508\)
\(x=64844\)
