Question

x+5-1=26-14

x-6=79-20

52-25-3=x+5

52-12=x-19+20

5.x+1=36

2.x-9=2.3.5+23

Answer 1

 x+5-1=26-14 
x+4= 12
x = 12-4
x = 8

x-6=79-20  debe estar mal copiado  x = 59+6 x= 53  no da

52-25-3=x+5 idem noda fijate como copiaste

52-12=x-19+20

5.x+1=36   5x = 36-1= 35  
5x = 35
x= 35 ÷5 = 7
x = 7

2.x-9=2.3.5+23
2x-9= 30+23
2x= 53+9= 62
x=62÷2 = 31
x=31
