Question

3º)Simplifique as Expressões algébricas.

A)15z+3-9z

B)7.(x+4)-16

C)9a+5-8+7a

D)5.(4b-3)-37b

E)(54w+18)+2.(5-7w)

F)(8+6t).5-(27t-3)+4

Answer 1

15z-9z=-3 6z=-3 z=-1/2
7x=-28+16 7x=-12 x=-12/7
9a+7a=8-5 16a=3 a=3/16
20b-37b=15 17b=15 b=15/17
54w-14w=-18-10 40w=-28/40 w=7/10
30t-27t=40+3-4 3t=43-4 3t=39 t=13
