The correct answer would be:
A) Sunbathers at a free suntan lotion booth on a popular beach were asked about their favorite suntan lotion.

Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
You can factor this by grouping! We will need to group the trinomial into the expression (k^2 + k)(-2f^2 + f). Now factor from THOSE. k(k + 1)f(-2f + 1).
I put the solution on the paper
542(1+1/4)
542(4/4+1/4)
542(5/4)
677.5
