(1): 4x - 6 = 18

2): 5x - 20 = 3x - 8

3) 3 - 2x = 4x + 8

Answer 1

(1): 4x - 6 = 18
4x = 18 +6
4x = 24
X = 24/4
x= 6


2): 5x - 20 = 3x - 8
5x - 3x = - 8 +20
2x = 12
x = 12/2
x =6


3) 3 - 2x = 4x + 8
3 - 8 = 4x + 2x
-5 = 6x
x = - 5/6

Answer 2

(1): 4x - 6 = 18

4x = 18  + 6
4x = 24
x = 24 ÷ 4
x = 4

2): 5x - 20 = 3x - 8

5x - 3x = -8 + 20
       2x = + 12
         x = 12 ÷ 2
         x = 6
          
3) 3 - 2x = 4x + 8

-2x -4x = +8 -3
      -6x = 5
         x = -5/6
         x = -0.833
