For this one, the best way to do it is write out you formulas, then solve for the first one and see if it works for the second one.
I am going to use <em>h </em> for hamburgers and <em>d</em> for drinks to make it easier.
2h+5d=8
2h+3d=6
So what I did was make the drinks 1, this way you can see if you need to raise it or if the hamburgers could come out even. When you do that here is what it looks like:
2h+5(1)=8
2h+5=8
2h=3
h=1.50
So here is what you have as of now
h= 1.50 and d= 1
now plug that into the next problem
2h+3d=6
2(1.50)+3(1)=6
3+3=6
So that is your answer
Hamburgers are $1.50
and Drinks are $1
Hope this helps!

The equation for this would be 0.2x=3. Divide each side by 0.2 and you should get 15. That is the original price of the mirror.
2x+3+51 = 100
2x+54=100
2x= 46
X=23
