Question

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

Answer 1

Respuesta:

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

3x+6 + 2x-2 = 4x-8

         5x + 4 = 4x - 8

        5x - 4x = -8 -4

                x = -12

Answer 2

Explicación paso a paso:

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

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

expandir.

3(x+2)

= 3x+3•2

= 3x+6

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

expandir.

2(x-1)

= 2x-2•1

= 2x-2

= 3x+6+2x-2

simplificar.

3x+6+2x-2

= 3x+2x+6-2

= 5x+6-2

= 5x+4

Desarrollar 4(x-2)

4(x-2)

= 4x-4•2

= 4x-8

entonces.

5x+4= 4x-8

restamos 4 de ambos lados.

5x+4-4= 4x-8-4

simplificar.

5x= 4x-12

restamos 4x de ambos lados.

5x-4x= 4x-12-4x

simplificar.

x= -12

espero te ayude:)
