Question

Solve for g .

g + (-5) = 27
g =

Solve for h .

-18 + h = 28
h =

Solve for a .

5.4 = a - (-1.8)
a =

Answer 1

for the first one you can add 5 on both sides so you gonna have : g - 5 = 27
+5 +5
⇒ g = 27 + 5 =32
for the second one you can add 18 on both sides : -18 + h = 28
+18 +18
⇒ h = 28 + 18 = 46
and as same in the last one : a= 3.6

Answer 2

g + (-5) = 27
⇒ g = 27- (-5)
⇒ g = 27+5
⇒ g= 32

-18 + h = 28
⇒ h= 28- (-18)
⇒ h= 28+18
⇒ h= 46

5.4 = a - (-1.8)
⇒ a= 5.4+ (-1.8)
⇒ a= 5.4- 1.8
⇒ a= 3.6
