Question 1209916
<pre>

{{{matrix(2,3,

2(4x+1^""^""),""="",9,
2(4(7/8)+1^""^""), ""="", 9   ))}}}
Cancel the 4 into the 8 and get 2 on the bottom:

{{{matrix(1,3,


2(7/2+1^""^""),""="",9)}}}

Distribute the 2 into the {{{7/2}}} and also into the {{{1}}}

{{{matrix(1,3,


2(7/2)+2(1),""="",9)}}}

Cancel the 2's, get 7, and then, 2 times 1 is 2:

{{{matrix(1,3,


7 + 2,""="",9)}}}

And finally

{{{matrix(1,3,


9,""="",9)}}}
