The other expression gives us a solution of <em>-</em><em>9</em><em> </em><em>=</em><em> </em><em>x</em><em>,</em><em> </em>and we do not want that; this one gives us <em>6</em><em> </em><em>=</em><em> </em><em>x,</em><em> </em>and THIS is what we are looking for.
I am joyous to assist you anytime.

Hope this helped and have a good day
