Solve linear system by any method

15x-27y=41
21x+4y=17
Click to expand...

Elimination method:

Multiply the top equation by 7 and the bottom equation by -5. Add the two equations together, thus eliminating the x variable.

Solve for y.

Plug the result for y back into one of the equations to solve for x.

Check by plugging both x and y values into the other equation to see if they work there.
 
Having some issues...

ok...

so here is what I come up with
105x-189y=287
-105x-20y=-85

(-209y/-209)=(202/-209)
15x-27(202/-209)=26 20/209

Am I to reduce this so that I can plug it in to y?
 
Yes. Solve for 'x'. Check your results in the ORIGINAL equations.
