Answer:
g is equal to -3
Explanation:
from the question , we have
-g - 15 = -12
to find the value of g, the first step to take is to collect the like terms
-g - 15 = -12
we have,
-g = -12 + 15 ( minus will change to plus when crossing over the equal = sign)
so,
-g = 3
since we are asked to find the value of g and not -g
we divide both sides by - sign
-g/- = 3/-
g = -3
to check if your answer is correct put g = -3 in the original equation
-g - 15 = -12
-(-3) - 15 = -12
-12 = -12....... proved
