Explanation:
When we have variables on both sides we look for the coefficient that is lower than the two and reverse the sign.
Example:
1x+ 4 = 2x+3
We reverse 1x sign because it is lower so we will be subtracting
2x-1x = 1x
1x+3=4
We would then solve for x.

Let's begin to solve! </span>
Step 1:You would look for the coefficient or variable that is less and reverse the sign.
In this question the lower number is -x and so we would reverse the sign to add.
x+x= 2
Step 2: We now have
2x+3 = -5
Step 3: We will subtract 3 to -5 to find X
-3+-5= -8
Step 4:2x = -8
Divide both sides by two fo find x
Our answer:

-
Summary:
We first looked for the lower coefficient (in this case variable). We then flipped the sign and solved for x

Hi there,
If what you are trying to find is the volume, then:
Here's the equation:
4×6×2 = 48 --- volume of the smaller rectangular box
12×14×2 = 336 --- volume of the bigger box
48 + 336 = 384 --- the total volume of the figure
Hope this helped :P
