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
Answer:

So, since there are 37 children in each bus, and 7 busses, we need to multiply the two together.

Answer:
What is the question
Step-by-step explanation:
X + y = 150
x = y + 100
2y + 100 = 150
2y = 50
y = 25
shoes are 25 hoodie is 125
Answer:
( -1 , 1 )
Step-by-step explanation:
(x1,y1) = (5,9)
(x2,y2) = (-7,-7)
=(-7+5/2 , -7+9/2)
= (-1,1)
