The 2 equations are
-2x + y = -17 ---1)
3x + y = 23 ---2)
we need to have the same coefficient for one of the variables.
Already y variable has the coefficient of 1 for both equations so we can use the equations as it is.
2) - 1) subtract 1) from 2)
3x-(-2x) + y -y = 23-(-17)
5x = 40
x = 8
substituting x = 8 in the 2nd equation
3*8 + y = 23
24 + y = 23
y = -1
solution - (8,-1)
120 servings.
You do this by multiplying 30 by 4 (because each pound can make 4 servings as represented by 1/4 pound) Hope you understand I'm not good with explaining.
Ultimately Woodrow Wilson's preferred direction was not to get involved
with the internal affairs of the USA's near neighbors in Latin America.
However events unfolded that meant his governments ended up being as
interventionist as those of Teddy Roosevelt, for example occupying Haiti
and the Dominican Republic. These activities were not intended plans of
Wilson's in the way that Roosevelt set out to police Latin America but
nonetheless the impact was the same.
