6x - 2x = 16
4x = 16 |divide both sides by 4
<h3>x = 4</h3>
so you have your two equations 3x+7=5x-23 and solve for x which is your "number" leaving the answer to be <u>x=15</u>
Hi!
When following the order of operations, A. Parantheses (or brackets) come first. =)
So this question you just add..... but this is irrational because it does not terminate meaning the decimal doesnt end home this helped have an amazing day!

![\\ \sf{:}\implies side=\sqrt[3]{14}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%7B%3A%7D%5Cimplies%20side%3D%5Csqrt%5B3%5D%7B14%7D)

Now

Cut it into 10 parts as per question(Open side means five sides hence it will be 5×2=10)

Now divide by previous side
