Question

Resuelve las siguientes ecuaciones obtenidas en el valor de la incognita:
a) 4x+2x+3=27
b)5x-8x-3(x-2)=-6
c)4y-4(5y+4)=2y+2
d)12+4(m-3)=6(5-m)
e)5x+4=3-4(x+2)​

Answer 1

Respuesta:

a) 4x+2x+3=27

(6x+3)−{27}=0

6x−24=0

(6)⋅x+(−24)=0

x=−(−24)6

x=−(6)⋅(−4)(6)=4

b)5x-8x-3(x-2)=-6

−3x−(3x−6)−{−6}=0  

(−6x+6)−{−6}=0

−6x+12=0

(−6)⋅x+(12)=0

x=−(12)−6

x=−(6)⋅(2)(6)⋅(−1)=2

c)4y-4(5y+4)=2y+2

4y−(20y+16)−{2y+2}=0

(−16y−16)−{2y+2}=0

−18y−18=0

(−18)⋅y+(−18)=0

y=−(−18)−18

y=−(18)⋅(−1)(18)⋅(−1)=−1

d)12+4(m-3)=6(5-m)

12+4⋅(m−3)−{6⋅(−m+5)}=0

12+(4m−12)−{−6m+30}=0

4m−{−6m+30}=0

10m−30=0

(10)⋅m+(−30)=0

m=−(−30)10

m=−(10)⋅(−3)(10)=3
