Question

determinar el valor de x en las ecuaciones
4x=2x-12

8x-24=5x

7xmas12=4x-17

Answer 1

Resolver.

4x = 2x - 12
4x - 2x = - 12
2x = - 12
x = - 12/2
x = - 6


8x - 24 = 5x
8x - 5x = 24
x = 24
x = 24/3
x = 8


7x + 12 = 4x - 17
7x - 4x = - 17 - 12
3x = - 29
x = - 29/3

Answer 2

4x=2x-12
4x-2x=-12
2x=12
x=12/2= 6

8x-24=5x
8x-5x=24
3x=24
x=24/3 =8

7x+12=4x-17
7x-4x+12=-17
3x=-12-17
3x=-29
x= -29/3
