a) x+5= 12

x + 5 - 5 = 12 - 5
x = 12 - 5
x = 7

b) 15 + x + 6
15 - 6 = x + 6 - 6
15 - 6 = x
9 = x

c) 19 = 7 + x
19 - 7 = 7 - 7 + x
19 - 7 = x
12 = x
Hey there, Lets solve this problem together. 

Equation (A) = [tex]x+5= 12[/tex] 

[tex]x + 5 - 5 = 12 - 5 x = 12 - 5 x = 7[/tex] 

Equation (B) = [tex]15= x+6[/tex] 

[tex]15 - 6 = x + 6 - 6 15 - 6 = x 9 = x[/tex] 

Equation (C) = [tex]19= 7+x[/tex] 

[tex]19 - 7 = 7 - 7 + x 19 - 7 = x 12 = x[/tex]
