anonymous · Answer

multiply the first one by 4
12 + 4y = 56
as you see you have two equations which are the same..
you can for example subtract one from another to get 0=0 
which is true.

infinite number of solutions

anonymous · Answer

$$y=14-3x$$ plug in y into the second equation so you have$$12x+4(14-3x)=56$$ solve for x $$12x+56-12x=56 $$ so that  $$0=0$$  . This is a true statement so you have an infinite amount of solutions
