Question

If u can help with this question, the options for both x' s are -8,-7,-6,-5,-4,-3,-2,-1,1,2,3,4,5,6,7,8

Answer 1

1x + 1y = 100....multiply by -3/8
3/8x + 7/8y = 2000

no need to multiply the other equation by anything....the x's will cancel because one will be -3/8x and one will be 3/8x
