Question

ecuacion lineal 7-6(x-1)=7+2(7x-4)​

Answer 1

Respuesta:

7-6(x-1)=7+2(7x-4)​

$7-6\left(x-1\right)-7=7+2\left(7x-4\right)-7\\-6\left(x-1\right)=2\left(7x-4\right)\\\frac{-20x}{-20}=\frac{-14}{-20}\\\\x=\frac{7}{10}$

Answer 2

Respuesta:

7-6(x-1) = 7+2(7x-4)​

7-6x+6 = 7+14x-8

13-6x = -1+14x

(-6-14)x = -1-13

-20x = -14

-20x/-1 = -14/-1

20x = 14

20x/2 = 14/2

10x = 7

10x/10 = 7/10

x = 7/10
