Question

Please help me with these 19 and 20 and tell me what you use to get the answer

Answer 1

36 + h = 75...subtract 36 from both sides
h = 75 - 36
h = 39

-176 = h + (-219)
-176 = h - 219....add 219 to both sides
219 - 176 = h
43 = h

Answer 2

36+h=75   (subtract 36 from both sides in order to find h)
h=75-36
h=39

-176=h+(-219)
-176=h-219    (add 219 to both sides in order to solve for h)
43=h
