Question

Математика: 110*х=9900,у*78=19734, 1800: z=45,u*261=147,50*(v-173)=2500,1748: w+77=123

ubbdfqhdu · Answer

110*х=9900 u/261=147
x=9900/110 u=147*261
   x=90 u=38367
50*(v-173)=2500
у*78=19734 v=2500/50+173
у=19734:78 v=223
у=253 1748/w+77=123
1800:z=45 w=1748/(123-77)
z=1800/45 w=38
z=40
