If x = y+3+4.5x and y = x+18, what is the value of x/y ?  Select the correct option.
A) -6/5 B) -7/20. C) 1/4. D) 5/6. E) 1.5
Given x = y+3+4.5x --&gt; Eq 1   and y = x+18 --&gt; Eq 2   Here we are asked to find the value of X/Y ?   If you observe eq 1 , then we can understand that if we take Y as X then we get X value very quickly   Let's take X/Y = 1/4 =&gt; 4X = Y - eq 3.   Sub this value in eq 1 =&gt; we get X = 4X + 3 + 4.5 X   =&gt; - 7.5X = 3   =&gt; X = -2/5 --&gt; Sub X in eq 3 to get Y, we get Y as -8/5.   X/Y = -2/5 / -8/5 =&gt; 1/4. we get the same value again.   Answer:option 1/4. is correct answer
