2+5+X=16+12
X-15=24+13-12

Answer 1

Respuesta:

Explicación paso a paso:

Primera

X=72-18-3

x=51

Segunda

x=10+6+3

x=19

Tercero

x=-5+2+18+13

x=28

Cuatro

X=16+12-5-2

x=21

Quinto

x=15+24+13-12

x=40

Answer 2

Respuesta:

3+x = 72 - 18

3+x = 54

x= 54 - 3

x = 51

x-10 = 6+3

x-10 = 9

x = 9+10

x = 19

x+5-2 = 18+13

x+3 = 31

x = 31-3

x = 28

2+5+x = 16+12

7+x = 28

x = 28-7

x = 21

x-15 = 24+13-12

x-15 = 37-12

x-15 = 25

x = 25+15

x = 40
