Let's call the number x. So four times the number minus five would look like

4x-5

Twice the number plus three would look like

2x+3

Now make the two equations equal

4x-5=2x+3

I'm going to subtract 2x from each side

2x-5=3

Now I'm going to add five to each side

2x=8

Now divide both sides by 2

x=4

To double check, just plug back into the original equations

4(4)-5=11

2(4)+3=11

They are equal, so the answer is x=4.
