a. 17 +x=1
b. x+39=0
c. 12-x =5
d.-x+12=1​

Answer 1

a. 17 + x = 1 => x = 1 - 17 = -16

b. x + 39 = 0 => x = -39

c. 12 - x = 5 => x = 12 - 5 = 7

d. -x + 12 = 1 => x = 12 - 1 = 11

Answer 2

Explicație pas cu pas:

a. 17 + x = 1

x=1 - 17

x = 16

b. x+39=0

x = 0-39

x =-39

c. 12-x=5

- x = 5-12

-x= -7

x=7

d. -x+12=1

-x= 1-12

-x=-11

x=11
