a)x-5+2x c)7c+4-8-3c e)4s+4s.(20:5)+6
b)6.(2-d) d)-9y+2.(5y-2) f)(4+3t).3-8t-7

Porfavor me Ajudemmm Agradeço muito ....

Answer 1

a)x-5+2x ==> 3x - 5
=======================================
b)6.(2-d) ==> 12 - 6d
=======================================
c)7c+4-8-3c ==> 4c - 4
=======================================
d)-9y+2.(5y-2) ==> - 9y + 10y - 4 ==> y - 4
====================================================
e)4s+4s.(20:5)+6 ==> 4s + 4s.4 + 6 ==> 4s + 16s + 6  ==> 20s + 6

f)(4+3t).3-8t-7
