Answer 1

Respuesta:

espero te ayude :)

Explicación paso a paso:

1). 6a -2=4a+12

   6a-4a = 12+2

        2a = 14

          a= 14/2

          a= 7

2). 7W-18=5W+8

 7W-5W = 8+18

        2W = 26

           W= 26/2

           W= 13

3). 4e+5=2e+9

  4e-2e =9-5

        2e = 4

          e = 4/2

           e= 2

4). 6t+8=5t+17

6t-5t = 17-8

         t = 9

5).  7u+2=5u+26

  7u-5u = 26-2

        2u = 24

          u = 24/2

u =12

6).     12P=7P+20

12P - 7P = 20

     5P = 20

        P= 20/5

P =4

7). 13d-28=8+12

13d = 8 + 12 + 28

        13d = 48

           d = 48 / 13

           d = 3.69 = se redondea d= 3.7

8). 2.5f-5=1.5f+10

f = 10 + 5

            f= 15

9).          5/6 Y=1/2 Y+2/3

 5/6 Y - 1/2 Y = 2/3

              1/3 Y = 2/3

                    Y = 2/3 entre 1/3

                   Y = 1/3

 

Answer 2

6a -2=4a+12

6a - 4a = 12 + 2

2a = 14

a = 14/2

a = 7

7W-18=5W+8

7W - 5W = 8 + 18

2W = 26

W = 26/2

W = 13

4e+5=2e+9

4e - 2e = 9 - 5

2e = 4

e = 4/2

e = 2

6t+8=5t+17

6t - 5t = 17 - 8

t = 9

7u+2=5u+26

7u - 5u = 26 - 2

2u = 24

u = 24/2

u = 12

12P=7P+20

12P - 7P = 20

5P = 20

P = 20/5

P = 4

13d-28=8+12 (no se si aqui te faltó colocar una variable en la igualdad)

13d = 20 + 28

13d = 48

d = 48/13

2.5f-5=1.5f+10

2.5f - 1.5f = 10 + 5

f = 15

5/6 Y=1/2 Y+2/3

5/6Y - 1/2Y = 2/3

5/6Y - 3/6Y = 2/3

2/6Y = 2/3

1/3Y = 2/3

Y = 2/3 / 1/3

Y = 6/3

Y = 2
