Question

Resolva as equações:

a) x + 15 = 35
b) 3y + 4 = 28
c) 2. (w - 2) = 16
d) 3z – 10 = z +60

Answer 1

Resposta:

A) x= 35-15

x= 20

B) 3y= 28-4

3y= 24

y= 24÷3

y= 8

C) 2w-4= 16

2w= 16+4

2w= 20

w= 20÷2

w= 10

D) 3z -z = 60+10

2z= 70

z= 70÷2

z= 35

Answer 2

A)

x= 20

B)

y= 8

C)

w= 10

D)

z= 35
