Solve the following system and show all of your work.
x − 2y = 14
x + 3y = 9

My answer is

x-2y=14
x=2y+14

Put this value of x into second equation

2y+14+3y=9
5y+14=9
5y=9-14
y=-5/5
y=-1

now put y= -1 into the first equation

x-2(-1) =14
x+2=14
x=12

Am i right? :)

if you want to be sure all you have to do is to put the values of x  and y in both equtions and find the results
