Answer 1

Respuesta:

3) e = 22

4) e = 10

Explicación paso a paso:

-(30 - 8x) + (9x -8) + (2x-20) = 360

-30 + 8x + 9x - 8 + 2x - 20 = 360

8x + 9x + 2x = 360 + 30 + 8 + 20

19x = 418

x = 418/19

x = 22

-(6x - 150) + 60 - (5x - 80) = 180

-6x + 150 + 60 - 5x + 80 = 180

-6x - 5x = 180 - 150 - 60 - 80

-11x =-110

x = -110/-11

x = 10
