Question

RESOLVER LAS SIGUIENTES ECUACIONES CON MÁS DE UNA x
A) 7x = 4x – 6
B) – 6x = - 24 + 2x
C) x – 8 = 4 – x
D) 3x – 10 = 18 – x
E) 7x + 8 = 3x – 4
F) – 2 – 3x + 5 = - 5 – 8x + x

Answer 1

Respuesta:

A) 7x = 4x-6

7x-4x = -6

3x = -6

x = -6-3

x = -9

B) -6x = -24+2x

-2x-6x = -24

-8x = -24

x = -24+8

x = -16

C) x-8 = 4-x

x+x = 4+8

2x = 12

x = 12-2

x = 10

D) 3x-10 = 18-x

3x+x = 18+10

4x = 28

x = 28-4

x = 24

E) 7x+8 = 3x-4

7x+3x = -4-8

10x = -12

x = -12-10

x = -22

F) -2-3x+5 = -5-8x+x

-3x+8x-x = -5-5+2

4x = -8
