matrix%281%2C5%2C3m%2C+add%2C+10%2C+is%2C+16%29

Change the word "add" to +
Change the word "is" to "="

matrix%281%2C5%2C3m%2C+%22%22%2B%22%22%2C+10%2C+%22%22=%22%22%2C+16%29

Add -10 to both sides:


--------------------------


That's     matrix%281%2C3%2C3m%2C%22%22=%22%22%2C+6%29

Now divide both sides by the coefficient of m, which is 3

           matrix%281%2C3%2C3m%2F3%2C%22%22=%22%22%2C+6%2F3%29

Cancel on the left and divide on the right:

           matrix%281%2C3%2Ccross%283%29m%2Fcross%283%29%2C%22%22=%22%22%2C+2%29

           matrix%281%2C3%2Cm%2C%22%22=%22%22%2C+2%29
