Question

A) X+3-2=8-3

B) 6X-8=2X+12

C) 9+21+3X=45+15

D) 18X-43=65

E) 2X+12=24

F) 16+X+4X=20+36

Answer 1

A) x+3-2=8-3
x = 8+2-3-3
x = 10-6
x = 4

B) 6X-8=2X+12
6x-2x = +12+8
4x = 20
x = 20/4
x = 5

C) 9+21+3X=45+15
3x = 45+15-9-21
3x = 60-30
3x = 30
x = 30/3
x = 10

D) 18X-43=65
18x = 65+43
18x = 108
x = 108/18
x= 6

E) 2X+12=24
2x = 24-12
2x = 12
x = 12/2
x = 6

F) 16+X+4X=20+36
x+4x = 20+36-16
5x = 40
x = 40/5
x = 8

Answer 2

a- x=8-3-3+2
     x= 8+2-3-3
     x=4

b- 6x-2x=12+8
    4x=20
      x= 20/4
     x=5
c- 3x=45+15-21-9
    3x= 30
    x=30/3
   x=10
d-18x=65+43
    18x= 108
    x=108/18 
    x=6
e- 2x=24-12
     2x=12
       x=12/2
     x=6
f- 5x=20+36-16
   5x=40
    x=40/5
    x=8
espero ter ajudado :)
