Answer 1

Answer:

so I don't know how to to take an image but I can try to explain

so here it goes

you can use either elimination method or the substitution method if you use the elimination method then you will have to either pick between using the X coordinate or the y coordinate I choose the X coordinate so the top equation multiply by 2 and the lower equation x by 3 you will end up with 6 x plus 16 y is equals to 14 and 6 x - 6y is equals to -30 subtract the both equations and end up with 0 + 22 y is equals to 44 hence
