porfavor ayudenme a resolverlo todo ,doy muchos puntos si lo resuelves

Answer 1

1) 2x+10+x+25+x+35=270
2x+x+x+10+25+35=270
4x+70=270
4x=270-70
4x=200
x=50

enzo= 2(50)+10=110
tito=x+25= 75
rosa=x+35= 85

2) 2x+x+1+x+1+x+3x+1+2x+1=24
10x+4=24
10x=24-4
x=20/10
x=2

3) 4x+x=35... 5x=35... x=7
y+3=0... y=-3
2,5b=15... b=15/2,5... b=6
8+3a=5+a... 3a-a= -8+5... 2a=-3... a=-3/2... -1.5
-3z-1=20
-20-1=3z
-7=z
