Question

2)Resolva:
F) -2b+10=0
G)-4z+12=-12
H)-5t+20=35
I)-8z+10=-6

Mim ajudem...

Answer 1

f) -2b = -10 (-1)

2b = 10

b = 10/2

b = 5

g) -4z = -12-12

-4z = -24 (-1)

4z = 24

z = 24/4

z = 6

h) -5t = 35 - 20

-5t = 15 (-1)

5t = -15

t = -15/5

t = -3

i) -8z = - 6 - 10

-8z = -16 (-1)

8z = 16

z = 16/8

z = 2
