can you show me the next step? then I think I can from there... I understand a little better

so we open up the brackets and gather like terms 3y+21-5y=25 21-2y=25 -2y=3 y=(-3/2) Now plug this into the second equation to find out what x equals

Then to check your work plug in the x and y into both equations and if the answer is correct then you know u got the correct answer
