Question

a b c d equação valo de x

Answer 1

Ola!

a) 5x - 20 = 20
5x = 20 + 20
5x = 40
x = 40/5
x = 8

b) 16x - 100 = 60
16 x = 60 + 100
16 x = 160
x = 160/16
x = 10


c)3x/15 = 4
3x = 4 . 15
3x = 60
x = 60/3
x = 20

d) 800x + 200 = 200
800x = 200 - 200
800x = 0
x = 0/800
x = 0

espero que esteja tudo certinho, tenha uma boa noite!

Answer 2

a)

5x-20=20

5x=20+20

5x=40

x=40/5

x=8

b)

16x-100=60

16x=60+100

16x=160

x=160/16

x= 10

c)

3x/15=4

3x=4*15

3x=60

x=60/3

x=20

d)

800x+200=200

800x=200-200

800x=0

x=0/800

x=0
