The first graph is what i would think
well it would be 18/9 and that would simplify to 2 because if u divide both by 9 u get 2/1 which is 2
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>
