43.)
a. There is an s amount of shoes, because s is the total amount of shoes
b. x is the number of shoes, so x - 1/2 = s
44.)
2s + 7 = x
45.)
the variable s is the total amount of shoes Pete has and 8 don't fit him anymore (or got ruined) so he threw them away... x - 8
46.)
The expressions y + 4 and 1y + 4 are equivalent, because a variable always has a hidden (1) next to it like (1)y and any positive number multiplied by 1 always stays the same.
I hope i helped : )

Answer:
the answer is 30
Step-by-step explanation:
because it is an equilateral triangle all sides are the same so if you set 3x+15 equal to 7x-5 and solve for x you get 4x=20 and x= 5
when you plug 5 in to each equation you get 30 for both sides and so it proves that the answer is 30
X= -6
