Question

Plz help me to solve this


plz plz​

Answer 1

Answer:

3.

a. 3x = 30

 x = 30/3

 x = 10

b. 10x + 150 = 450

    10x = 450 - 150

    10x = 300

     x = 300/10

     x = 30

c.  2 + x = 25

    x = 25 - 2

    x = 23

d.  45 - 3y = 15

    3y = 45 - 15

    3y = 30

     y = 30/3

     y = 10

e. 7a/6 = 49

   7a = 49 x 6

   7a = 294

     a = 294/7

     a = 42

f. 3x/2 - 5 =  13

   3x/2 = 13 + 5

     3x/2 = 18

    3x = 18 x 2

    3x =  36

      x = 36/3

      x = 12

g.  (8m + 3)/4 = 1

      8m + 3 = 1 x 4

      8m + 3 = 4

      8m =  4 - 3

      8m = 1

      m = 1/8
