Answer:
<u>x = 36</u>
Here's how I got that:
<em> - Group like terms -</em>
x - 2 + 2x + 4 + 2x - 2 = 180
↓
5x - 2 + 4 - 2 = 180
↓
5x = 180
<em> - Divide both sides by 5 - </em>
<em> </em> 5x/5 = 180/5
↓
<em> </em><u><em>x </em></u><u>= 36</u>
<em>~ That's all folks ~</em>

x => Hamburgers
y => Hot dogs
x + y = 26
3.5x + 2y = 70
-2x - 2y = -52
3.5x + 2y = 70
-----------------------
1.5x = 18
x = 18 / 1.5 = 12
y = 26 - 12 = 14
They sold 12 hamburgers and 14 hot dogs
