Question

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

Answer 1

Resposta:

3 ( x - 2) = 2x - 4

3x-6=2x-4

3x-2x=-4+6

x=2

2 (x - 1) = 3x + 4

2x-2=3x+4

2x-3x=4+2

-x=6

x=-6

Answer 2

Resposta:

3 (x - 2) = 2x - 4

3x-6= 2x-4

3x-2x= -4+6

x= +2

2 (x - 1) = 3x + 4

2x-2= 3x+4

2x-3x= +4+2

-x= +6

x= -6
