\(2016\times105-2016\times4-2016\)
\(=2016\times\left(105-4-1\right)\)
\(=2016\times100\)
\(=201600\)
\(x\times24+x\times6=240\)
\(x\times\left(24+6\right)=240\)
\(x\times30=240\)
\(x=240:30\)
\(x=8\)
\(x-167\times15=167\times185\)
\(x-2505=30895\)
\(x=30895+2505\)
\(x=33400\)
\(173\times105+173\times96-173\)

1. 2016 x 105 - 2016 x 4 - 2016
= 211680 - 8064 - 2016
= 203616 - 2016
= 201600
2. X x 24 + X x 6 = 240
X x (24 + 6) = 240
X x 30 = 240
X = 240 : 30
X = 8
3. X - 167 x 15 = 167 x 185
X - 2505 = 30895
X = 30895 - 2505
X = 28390
4. 173 x 105 + 173 x 96 - 173
= 18165 + 16608 - 173
= 34773 - 173
= 34600
X x 5 = 235 X : 3 = 173
X = 235 : 3 X = 173 x 3
X = 47 X = 519
178 - 35 : x = 173
35 : x = 178 - 173
35 : x = 5
x = 35 : 5
x = 7
Bài 1.
\(x\times15+x\times35=250\)
\(x\times\left(15+35\right)=250\)
\(x\times50=250\)
\(x=250:50\)
\(x=5\)
\(------\)
\(718-x\times5=173\)
\(x\times5=718-173\)
\(x\times5=545\)
\(x=545:5\)
\(x=109\)
\(-x-\dfrac{5}{21}=-\dfrac{173}{63}\)
\(-x=\left(-\dfrac{173}{63}\right)+\dfrac{5}{21}\)
\(-x=-\dfrac{158}{63}\)
\(x=-\left(-\dfrac{158}{63}\right)\)
`=>`\(x=\dfrac{158}{63}\)
173 - ( x - 49 ) = 27
x - 49 = 173 - 27
x - 49 = 146
x = 146 + 49
x = 195
Vậy x = 195
`92783-x:173=83723`
`=> x:173=92783-83723`
`=>x:173=9060`
`=>x=9060xx173`
`=>x=1567380`
