We are given with 7.5 moles of oxygen and 7.43 moles of nitrogen.To identify the chemical formula of the compound, we divide each numner by the smaller amount between the two. Hence, oxygen is approx. equal to 1 and nitrogen is equal to 1. Hence teh formula is NO or nitric oxide.
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

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

Answer:
x= 4
Step-by-step explanation:
We do like:
5x+2(1-x)=2(2x-1)
5x + 2 -2x = 4x -2
or 3x +2 = 4x -2
3x-4x +2 = -4x+4x -2
or -x +2= -2
and -x+2 -2 = -2 -2
or -x = -4
and x = 4 is the solution.
Have a good day.
