Question 252724
The first goal is to get all of the variable terms to the left side for each equation.


{{{5x-6y=7+7z}}} Start with the first equation.



{{{5x-6y-7z=7}}} Subtract 7z from both sides.


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


{{{2x+4y=29+3z}}} Move onto the third equation.



{{{2x+4y-3z=29}}} Subtract 3z from both sides.



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



So we now have the system



{{{system(5x-6y-7z=7,6x-4y+10z=-34,2x+4y-3z=29)}}}



Now let's use Cramer's Rule to solve this system
