a x ÷3= 7

a + x= ax=3.7

ax= 21

Answer 2

Resposta:

a)x/3=7

x = 3 * 7

x = 21

b)x/4=-3

x = -3 * 4

x = -12

c)2x/5=4

2x = 5 * 4

2x = 20

x=20/2

x =10

d)2x/3=-10

2x = -10*3

2x = -30

x = -30/2

x = -15

e)3x/4=30

3x = 30 * 4

3x = 120

x = 120/3

x=40

f)2x/5=-18

2x= -18*5

2x= -90

x = -90/2

x= -45
