Question

2x+7-3x= -3
6-4x-6x= -20
5x+7= x-5
-12+3x= 2. ( x-4)
3 (2x-1 )=4x+3

Answer 1

2x+7-3x=-3
   2x-3x =-3-7
        -x=-10
         x=10

6-4x-6x=-20
    -10x=-20-6
         x=-26/-10
         x=$\frac{13}{5}$

5x+7=x-5
 5x-x=-5-7
    4x=-12
     x=-12/4
     x=-3

-12+3x= 2.( x-4)
-12+3x=2x-8
 3x-2x =-8+12
          x=4

3(2x-1)=4x+3
    6x-3=4x+3
  6x-4x=3+3
      2x=6
       x=6/2
       x=3

Answer 2

2x + 7 -3x = -3
2x -3x = -3 -7
-x = -10
x = -10/-1
X = 10

6-4x-6x= -20
4x-6x= -20-6
10x= -26
x = -26/10 = 13/5

5x + 7= x -5
5x + x = -5 -7
6x = -12
x = -12/6
x = -2

-12 + 3x = 2(x-4)
-12 + 3x = 2x -8
3x -2x = -8 + 12
x = 4

3(2x-1)= 4x + 3
6x -3 = 4x + 3
6x -4x = 3 +3
2x = 6
x = 6/2
X = 3
