Answer 1

Explicación paso a paso:

1) 3x -5 = 4

3x= 4 + 5

3x = 9

x= 9/3

x= 3

2) 6x+3-7= 5x

6x -5x= 4

x= 4

3) 4x -5 = x + 7

4x - x = 7 + 5

3x= 12

x= 12/3

x= 4

4) 3x -8 +7x= 8

10x = 8 + 8

10x= 16

x= 16/10

x= 8/5

5) 2x -5 = 7 - x

2x + x = 7 + 5

3x= 12

x= 12/3

x= 4

6) 7x + 3 = 2x + 3

7x - 2x = 3 - 3

5x = 0

x= 0/5

x= 0

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

10x -3 = 21x + 14

-3 - 14= 21X - 10X

-17 = 11X

X= -17/11

8) 4X+ 2(5-1) = 3(2x+4)

4x + 8 = 6x + 12

4x - 6x = 12 -8

-2x = 4

x= 4/-2

x= -2
