Question

Cías es la comprobación de 2-[3-2(x+1)]=3x+2[x-1(3+2x)]

Answer 1

2-(3-2x-2)=3x+2(x-3-2x)
2-(3-2-2x)=3x+2(x-2x-3)
2-(1-2x)=3x+2(-x-3)
2-1+2x=3x-2x-6
1+2x=x-6
2x-x=-6-1
X=-7

COMPROBACIÓN:

2-(3-2(-7+1))=3(-7)+2(-7-1(3+2(-7)))
2-(3-2(-6))=3(-7)+2(-7-1(3-14)
2-(3+12)=3(-7)+2(-7-1(-11))
2-15=3(-7)+2(-7+11)
-13=3(-7)+2•4
-13=-21+8
-13=-13
