7 0

(7x) + 3 = 8
subtract both sides by 3.

7x = 5
divide both sides by 7 to isolate the variable, x.

x = 5/7

<h2>Explanation:</h2>

Hello, recall that you need to write complete questions in order to get exact answers. Here we have a missing diagram so I can help you in a general way. A prism is a three dimensional shape that has two identical ends (flat faces

) and the same cross section all along its length. A cube is a special type of prism having six identical square sides. So the volume of a prism given the length of a side as s is:

$V=s^3$
