its okay to be confused but show me an attempt and how i will tell you where u are going wrong

anonymous · Answer

multiply the second part by -4
9x+4y=14
24x-4y=-80
then 
   9x+4y=14
+ 24x-4y=-80

=32x=-64
=x=-64/32
x=-2


9(-2)+4y=14
-18+4y=14
4y=14+18
y =32/4
y=8

the answer is 
x=-2
y=8

anonymous · Answer

The process of above answer is wrong.Because if you want to multiply with -4 you need to do so in both the equations.better to solve the sum through substitution method.
y=20+6x........(1)
9x+4(20+6x)=14
or,9x+80+24x=14
or,33x=-66
x=-2
y=20-12=8
