Question

4)Resuelve las siguientes ecuaciones en Z:
a) 8 - (4-X) =9
b) 4Z - 5 = 9 + 2(Z +1)
c) 2 = 7 - (2Y - 3)
d) 4 - X - 2(X + 1) = -2X
e) 2(4 - Z) + 10Z = 40
f) 3(3X + 1) - (X -1) = 6(X +10)

Answer 1

Respuesta:

B) 4Z-5=9+2(z+1)

4z - 5 = 9 +2z +2

4z - 5 =11+ 2z

4z - 2z= 11 + 5

2z= 16

z = 8

E) 2(4 - Z) + 10Z = 40

8 - 2z + 10z= 40

8 + 8z = 40

8z = 40 - 8

8z= 32

z= 4

Answer 2

Respuesta:

a) x = 5 b) Z = 8 c) Y = 4 d) X = 3

e) Z = 4 f) X= 28

Explicación paso a paso:

a ) 8-(4-x)= 9

8-4+x = 9

x = 9-4 = 5

b) 4Z-5=9+2(Z+1)

4Z-5=9+2Z+2

4Z-2Z=9+2+5

2Z = 16

Z = 16/2 = 8

c) 2=7-(2Y-3)

2=7-2Y+3

2-7-3 = -2Y

-8 = -2Y

Y = -8/-2 = 4

d) 4-X-2(X+1)=-2X

4-X-2X-1 = -2X

3 = -2X+3X

X = 3

e) 2(4-Z)+10Z=40

8-2Z+10Z = 40

8Z = 40-8

Z = 32/8 = 4

f) 3(3X+1)-(X-1)=6(X+10)

9X+3-X+1 = 6X+60

8X-6X = 60-4

2X = 56

X = 56/2 = 28
