Answer 1

Answer:

1.  30         2.  5          3.   -2           4.      11/2

Step-by-step explanation:

1. x/2=5+ (x/3)

whole*6

3x=30+2x

3x-2x=30

x=30

2.   2(x-(3/2))=7

     2x-3=7

    2x=10

    x=5

3. 7(x-2)=2(2x-4)

   7x+14=4x=8

  7x-4x=8-14

    3x=-6

      x=-2

4.   21-3(x-7)=x+20

    21-3x+21=x+20

    42-3x=x+20

   42-20=x+3x

    22=4x

   x=22/4

   x=11/2
