Answer 1

Resposta:

x=4

x=6

x= -2

x=5

x= -25

x= -2

x=3/2

Explicação passo a passo:

6x=2x+16

6x-2x=16

4x=16

x=16/4

x=4

2x-5=x+1

2x-x=1+5

x=6

4x-1=3(x-1)

4x-1=3x-3

4x-3x= -3+1

x= -2

7(x-4)=2x-3

7x-28=2x-3

7x-2x= -3+28

5x=25

x=25/5

x=5

4(x+10)- 2(x-5)=0

4x+40-2x+10=0

4x-2x=-40-10

2x= -50

x= -50/2

x= -25

7(x-1) -2(x-5)=x-5

7x-7-2x+10=x-5

7x-2x-x= -5+7-10

4x= -8

x= -8/4

x= -2

3x-2(4x-3)=2-3(x-1)

3x-8x+6=2-3x+1

3x-8x+3x=2+1-6

*(-1)  -2x=-3   *(-1)

2x=3

x=3/2
