Question

ECUACIONES LINEALES

1) 3x+9+2x+1=40

2) 2(2x-1)-3(x-2)=64

Answer 1

3x + 9 + 2x + 1 = 40

3x + 2x = 40 - 1 - 9

5x = 30

x = 30/5

x = 6

Respuesta : 

x = 6

---------------------------------------------------------------------------
 
2 (2x - 1) - 3 (x - 2) = 64

4x - 2 - 3x + 6 = 64

4x - 3x = 64 - 6 + 2

x = 60

Respuesta : 

x = 60
