3 x + y = 243
2x – y = 1

3 to the power of x + y (not 3 x + Y) = 243
and 2x - y = 1 (not to the power of)

From the first equation, you can rearrange by taking logs on both sides.



Using the power law, we get:



Now, divide by log(3);





Now that you got two linear equations, can you work the rest out?

I hope it helped! :)

Thanks hey! Jip got it now!

No problem :)
