d)-18y-15y=

e)7x²+5y-6x²=

f)18m+14b-8b-30m=





me ajude por favor!!!​

Answer 1

Resposta passo a passo:

a)5x-7x=(5-7)x=-2x

b)-9a-6a=-(9+6)a=-15a

c)-50m+14m=(-50+14)m=-(50-14)m=-36m

d)-18y-15y=-(18+15)y=-33y

e)7x²+5y-6x²=(7-6)x²+5y=1x²+5y=x²+5y

f)18m+14b-8b-30m=14b-8b-30m+18m=(14-8)b+(-30+18)m=(14-8)b-(30-18)m=

6b-12m
