Ecuaciones en Z


1) 2(4 - 2)+10z = 40

2) 3y - 27 = 9y + 3

3) 8 = 3w - 4 + w

4) 2(-x + 1) + 5 = x + 10
​

Answer 1

Explicación paso a paso:

2(4 - 2) + 10z = 40

2(2)+10z=40

4+10z=40

10z=40-4

10z=36

x=36/10

3y-27=9y+3

-27-3=9y-3y

-30=6y

-30/6=y

-5=y

8 = 3w -4 + w

8+4=3w+w

12=4w

12/4=w

3=w

2(-x+1)+5=x+10

-2x+2+5=x+10

2+5-10=x+2x

-3=3x

-3/3=x

-1=x
