Answer 3

yup

Answer 4

What you want to do, is find a number that you can plug in for X that will make both of the equations equal; meaning both equations will have the same answer.

Here's some examples, Lets plug in 2 for X:
10(2+2)=5(2+8)
You start from left to right and begin in the parenthesis:
2+2=4
10(4)=40
2+8=10
10(10)=100
4 does not equal 100

Let's try 4 for X:
4+2=6
10(6)=60
4+8=12
5(12)=60
60 does equal 60

4=x
