Question

6) Resolver las siguientes ecuaciones
a) 2x - 7 = 5x +2
c) 6x +7 - 2x -x-3
b) 2x +3x - 8 = 8 + 2x
d) 5x + 15 = 2-3​

Answer 1

2x - 7 = 5x +2

- 7 - 2 = 5x - 2x

- 9 = 3x

-9/3 = x

-3 = x

6x +7 - 2x -x-3

6x + 7 = x - 3

6x - x =  - 7 - 3

5x =  -10

x = -10/5

x = -2

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

5x - 8 = 8 + 2x

5x - 2x = 8 - 8

3x = 0

x = 0/3

x = 0
