Answer 2

Respuesta:

Explicación paso a paso:

1. 120 + x + 80 +40=360

 240 + x = 360

x= 360-240

x= 120

2. 153 + 120 + 45 + x-12 =360

 318 + x-12 =360

306 +x=360

x= 360-306

x=54

3. 5x+8x+4x+3x=360

 20x=360

 x= 360/20

x= 18

4.2x+x+90+180-x=360

 2x+270=360

 2x=360-270

2x= 90

x=45

5. 60+100+180-x+180-x=360

 340 -2x+180 =360

 520-2x=360

 -2x= 360 -520

 -2x= -160

 x=80
