6.) 8 - (h (6 +16) -4) (18+%)+(-b - (8) = Daly-5) -119 +у). 2b 80 9) - 4/6 - 2) + 5 (5(-7) –​

Answer 1

1)-36+18х+20=18х-16=2(9х-8)
2)17(7-а)-90=119-17а-90=-17а+29
3)-12(х+4)+50=-12х-48+50=-12х+2=2(1-6х)
4)42-56-7у=-14-7у=-7(2+у)
5)21-4х+32=53-4х
6)8-(b+16)-2b=8-b-16-2b=-8-3b=-(8+3b)
7)-(18+b)+(-18-b)=-18-b-18-b=-2b-36=-2(b+18)
8)7(y-5)-(19+y)=7y-35-19-y=6y-54=6(y-9)
9)-4(6-x)+5(x-7)= -24+4x+5x-35=9x-59
