This doesn't make sense provide more info? :)
The second choice my dude
Hey there! :D
Slope intercept form: y=mx+b
4x-2y=9
Add 2y to the other side.
4x=9+2y
Subtract 9 on both sides.
4x-9=2y
Flip the equation over.
2y=4x-9 <== slope intercept form
I hope this helps!

X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
