Answer:
g = 5
Explanation:
The initial expression is:
12 = g - (-7)
So, we can rewrite the expression as:
12 = g + 7
Because two consecutive minus signs can be changed by a plus sign.
Now, we can subtract 7 from both sides as:
12 - 7 = g + 7 - 7
5 = g
Therefore, the solution of the equation is g = 5
