4x -8 = 2x +6

7x + 1 = 6x +6

5x -3 = 2x -9​

Answer 1

2x+5=27

2x=27-5

2x=22

x=22/2

x=11

4x -8 = 2x +6

4x-2x=6+8

2x=14

7x + 1 = 6x +6

7x-6x=6-1

x=5

5x -3 = 2x -9

5x-2x=-9+3

3x=-6

x=-6/3

x=-2

Answer 2

2x+5=27

2x=27-5

2x=22

x=11

4x-8=2x+6

4x-2x=6+8

2x=14

x=14/2

x=7

7x+1=6x+6

7x-6x=6-1

1x=5

x=5/1

x=5

5x-3=2x-9

5x-2x= (-9)+3

3x= -6

x= -6/3

x= -2
