Question

2x+8 = 3x
7 -4 = 9x - 10
x + 5 + 3x + 7 = 2x + 18
4x-9 + x = 2x + 8 -x + 3
15 - 2x + 1 = 8-2 + 3x​

Answer 1

Respuesta:

2x+8 = 3x

2x-3x = -8

-x = -8

x = 8

7-4 = 9x-10

-9x = -10-7+4

-9x = -17+4

-9x = -13

x = 13/9

x+5+3x+7 = 2x+18

x+3x-2x = 18-5-7

4x-2x = 18-12

2x = 6

x = 6/2

x = 3

4x-9+x = 2x+8-x+3

4x+x-2x+x = 8+3+9

6x-2x = 20

4x = 20

x = 20/4

x = 5

15-2x+1 = 8-2+3x

-2x-3x = 8-2-15-1

-5x = 8-18

-5x = -10

x = 10/5

x = 2

Aqui ya hice todos los ejercicios y los procedimientos para que entiendas. Espero te sirva
