Answer 1

A) 2x-3 = 33-x
2x+x = 33+3
3x = 36
  x = 36/3
x = 12

B) 7-2x = 4+x
-2x-x = 4-7
-3x = -3
x = -3/-3
x = 1

C) 5x-6 = 3-4x
5x+4x = 3+6
9x = 9
x = 9/9
x = 1

D) 9-3x = -5+4x
-3x-4x = -5-9
-7x = -14
x = -14/-7
x = 2

E) 7x+10 = 6x-5
7x-6x = -5-10
x = -15

F) -3x+8 = 5x+16
-3x-5x = 16-8
-8x = 8
x = 8/-8
x = -1

G) x-4+5x = 4x+8
x+5x-4x = 8+4
2x = 12
x = 12/2
x = 6

H) 25-3x = 2x+17
-3x-2x = 17-25
-5x = -8
x = -8/-5
x = 1,6

I) 14x+24 = 10x+2x+30
14x-10x-2x = 30-24
2x = 6
x = 6/2
x = 3

J) -x+3 = -2x+17
-x+2x = 17-3
x = 14

K) 0,5x-3 = -3,5+1,5x
0,5x -1,5x = -3,5+3
-1x = -0,5
x = -0,5/-1
x = 0,5

L) 2x-3 = x+5
2x-x = 5+3
x = 8

M) 3x-1 = -x+3
3x+x = 3+1
4x = 4
x = 4/4
x = 1
