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
