Question

-(7/22+x)+3/11*(x-1/2)
-(2/9-x)+5/18*(2/15+x)
7/19*(38-y)-(-y-5)
-2/23*(69+y)+(-7+y)

9/16(4/5-y)-(-1/20-y)
-8/21*(7/16+y)-(1/6+y)
7/18*(27/28+x)+(1/4-x) раскройте скобки и упростите выражение

Answer 1

-7/22-х+3/11х-3/22=-8/11х-5/11
-2/9+х+1/27+5/18х=1 5/18х-5/27
7/19*38-7/19у+у+5=14+12/19у+5=19+12/19у
-2/23*69-2/23*у-7+у=-6-2/23у-7+у=21/23у-13

9/16*4/5-9/16*у+1/20+у=9/20-9/16у+1/20+у=1/2+7/16у
-8/21*7/16-8/21*у-1/6-у=-1/6-8/21у-1/6-у=-1/3-1 8/21у
7/18*27/28+7/18*х+1/4-х=3/8+7/18х+1/4-х=5/8-11/18х
