Question

resolva as equações :

b)8x+2=6x+4
c)8p+3=21+2p
d)2p+p+3p=6
e)4y+20=3y-2y-10

Answer 1

b)8x+2=6x+4

   8x - 6x = 4 - 2

    2x = 2

      x = 2/2

      x = 1

c)8p+3=21+2p

  8p - 2p = 21 - 3

         6p = 18

           p = 18/6

           p = 3

d)2p+p+3p=6

   6p = 6

     p = 6/6

     p = 1

e)4y+20=3y-2y-10

  4y - 3y + 2y = - 10 - 20

3y = - 30

  y = -30/3

  y = - 10

Answer 2

Olá

b)

8x + 2 = 6x + 4

8x - 6x = 4 - 2

2x = 2

x = 2/2

x = 1

c)

8p + 3 = 21 + 2p

8p - 2p = 21 - 3

6p = 18

p = 18/6

p = 3

d)

2p + p + 3p = 6

6p = 6

p = 6/6

p = 1

e)

4y + 20 = 3y - 2y - 10

4y - 3y +2y = - 10 - 20

3y = - 30

y = - 30 /3

y = - 10
