RESUELVE ESTAS ECUACIONES ?

A) x + 5x - 4 = 18 - 2

6x - 4 = 16

6x = 20

x = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B6%7D%20" />

simplificamos la midad

x = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B3%7D%20" />

b) 3x - 2 + 7x = 7 - 1

10x - 2 = 6

10x = 6 + 2

10x = 8

x = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B10%7D%20" />

simplficamos la mitad

x = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20" />

c) 4(2x + 3) - 2x = 4x + 20

8x + 12 - 2 = 4x + 20

6x + 12 = 4x + 20

6x - 4x = 20 - 12

2x = 8

x = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B2%7D%20" />

simplificamos la mitad

x = 4 d) 34 = 3x - 6 + 2x

34 = 5x - 6

34 + 6 = 5x

40 = 5x

<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B5%7D%20" /> = x

simplificamso la quinta

8 = x

entonces x = 8

espero qte sirva suerte y saludos.
