Question 1165069
.



            I am  179%  sure that your second equation is written incorrectly in this post.


            I am  129%  sure that the correct writing is  THIS   y = (1/2)x + 3,   y = (-1/4)x-3



<pre>
Left sides of these equations are identical --- hence, their right sides are equal

    {{{(1/2)*x + 3}}} = {{{(-1/4)*x - 3}}}.


Multiply both sides by 4 to rid of the denominators.  You will get

    2x + 12 = -x - 12


Collect the terms with x in the left side; combine the constant terms on the right.

    2x + x = - 12 - 12


Combine like terms

    3x     = - 24


Hence,  x = {{{(-24/3)}}} = -8.


Then y = {{{(1/2)*(-8) + 3}}} = -4 + 3 = -1.


<U>ANSWER</U>.  x= -8;  y= -1.

Solved.



Plus the standard mantra is attached.
