5- Determine o valor das incógnitas:
​

Answer 1

Oi, tudo bem?

a) aX/3=24/6

6aX= 72

aX= 72/6

aX=12

b)8/Y= 50/25

50Y= 200

Y= 200/50

Y=4

c))1/4=7/Z

Z=28

e)2/X=5/10

10X=20

X=20/10

X=2

f)1,5/3=X/2

3X=3

X=3/3

X=1

g)X/5=6/10

10X=30

X=30/10

X=3

i)X+3/X-2=3/2

2.(X+3)=3.(X-2)

2X+6=3X-6

2X-3X=-6-6

-X=-12

X=12

j)X+1/5=X/3

3.(X+1)=5X

3X+3=5X

3=5X-3X

2X=3

X=3/2

k) 2/1=x-15/x

2x=x-15

2x-x=-15

x=-15

Espero ter ajudado!
