The given equations satisfy the given conditions. There are
2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
1/8 is greater because say you have 1/8 of a pizza you will get a bigger piece but if you had 5/7 it will be be 5 tiny pieces. so 1/8 is greater than 5/7
9 and 1/2 is the answer. We can find this by simply subtract 1 1/2 from 12.
