<PRE><B>Question 102645</B>
To find the ordered pair, simply plug in the given information



{{{2x-5y=-12}}} Start with the given equation



Since the first number of the pair is -1, this means x=-1


{{{2(-1)-5y=-12}}} Plug in x=-1



{{{-2-5y=-12}}} Multiply



{{{-5y=-12+2}}}Add 2 to both sides



{{{-5y=-10}}} Combine like terms on the right side



{{{y=(-10)/(-5)}}} Divide both sides by -5 to isolate y




{{{y=2}}} Divide


--------------------------------------------------------------

Answer:

So our answer is {{{y=2}}} 



So the second number of the pair is 2



So that means the ordered pair is (-1,2)



So the answer is C</PRE>
