Question

RESUELVE
A) 4(X-6)=12-(X+3)

B) -2(X+3)-4=18+4X

C) 2(3X+1)-X+6=2(X-1)

D) 6X-2(X-3)=12

Answer 1

solucion
A)
4(x-6)=12-(x+3)
4x-24=12-x-3
4x+x=12+24-3
5x=33
x=33/5

B)
-2(x+3)-4=18+4x
-2x-6-4=18+4x
-18-6-4=4x+2x
-28=6x
x=-28/6
x=-14/3

C)
2(3X+1)-X+6=2(X-1)
6x+2-x+6=2x-2
6x-2x-x=-2-6-2
3x=-10
x=-10/3

D)
6X-2(X-3)=12
6x-2x+6=12
4x=12-6
4x=6
x=6/4
x=3/2

saludos

Answer 2

A) 4(x-6) = 12-(x+3) 4x-24 = 12-x-3 4x+x = 9+24 5x = 33 x = 33/5 B) -2(x+3)-4 = 18+4x -2x- 6 -4 = 18+4x -2x-10= 18+4x -10-18= 4x+2x -28= 6x -28/6=x .... Simplificando -14/3=x C) 2(3x+1)-x+6 = 2(x-1) 6x+2-x+6 = 2x-2 5x+8 = 2x-2 5x-2x = -2-8 3x = -10 x = -10/3 D) 6x-2(x-3) = 12 6x-2x+6 = 12 4x = 12-6 4x = 6 x = 6/4... Simplificando x = 3/2
