​

Answer 1

Resposta:

A)x-3=7

x=7+3

x=10

B)x+4=10

x=10-4

x=6

C)x+101=300

x=300-101

x=199

D)x-279=237

x=237+279

x=516

E)x-8=-10

x=-10+8

x=-2

F)x+9=-1

x=-1-9

x=-10

G)3x=12

x=12/3

x=4

H)9x=18

x=18/9

x=2

I)35x=-105

x=-105/35

x=-3

J)7x-1=13

7x=13+1

7x=14

x=14/7

x=2

K)6x-10=2x+14

6x-2x=14+10

4x=24

x=24/4

x=6

L)6x=2x+28

6x-2x=28

4x=28

x=28/4

x=7
