ayuda​

Answer 1

Respuesta:

2−3+2(x+1)=3x+2(x−3−2x)

2 Simplifica  x-3-2xx−3−2x  a  -x-3−x−3.

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

2−3+2(x+1)=3x+2(−x−3)

3 Simplifica  2-3+2(x+1)2−3+2(x+1)  a  2(x+1)-12(x+1)−1.

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

2(x+1)−1=3x+2(−x−3)

4 Expandir.

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

2x+2−1=3x−2x−6

5 Simplifica  2x+2-12x+2−1  a  2x+12x+1.

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

2x+1=3x−2x−6

6 Simplifica  3x-2x-63x−2x−6  a  x-6x−6.

2x+1=x-6

2x+1=x−6

7 Resta xx en ambos lados.

2x+1-x=-6

2x+1−x=−6

8 Simplifica  2x+1-x2x+1−x  a  x+1x+1.

x+1=-6

x+1=−6

9 Resta 11 en ambos lados.

x=-6-1

x=−6−1

10 Simplifica  -6-1−6−1  a  -7−7.

x=-7

x=−7
