COLOQUEM TODAS AS CONTAS PFVVVVV

Answer 1

Resposta:

A) 9x=5

x=5/9

B) 3m=12

m=12/3

m=4

C) 3y+1=13

3y=13-1

3y=12

y=12/3

y=4

D) 9y-2=8y

9y-8y=2

y=2

E) 3y+1=2y

3y-2y= -1

y= -1

F) y-9=0

y=9

G) y-6=12

y=12+6

y=18

H) 5y=3y+8

5y-3y=8

2y=8

y=8/2

y=4

I) 3y=15

y=15/3

y=5

J) 5y=35

y=35/5

y=7

K) 3y=33

y=33/3

y=11
