Let x= apples and y= bananas
x+y= 20
.5x+.75y= 11.5
Solving For x
x= 20-y
.5(20+ y) + .75y= 11.5
10- .5y+ .75y= 11.5
-.5y+ .75y= 11.5-10
.25y=1.5
y= 1.5/ .25
y=6
therefore x= 14
14 apples and 6 bananas

Hi there!

I believe your answer is:

$\boxed{x-1+x-2+x}$

Here’s why:

⸻⸻⸻⸻ $\boxed{\text{Simplifying the Expression...}}\\\\3x+2+(-5)\\----------------\\\rightarrow 3x+2-5\\\\\rightarrow\boxed{3x-3}\\\\\text{This is not an answer choice, so we would find an expression equivalent to the one above.}$ ⸻⸻⸻⸻

$\boxed{2 +3x+5}\\\\\rightarrow 3x + 5 + 2\\\\\rightarrow \boxed{3x + 7}\\\\\text{This is \textbf{NOT} equivalent.}$

⸻⸻⸻⸻

$\boxed{x-1+x-2+x}}\\\\\rightarrow x+x+x -1-2\\\\\rightarrow \boxed{3x-3}\\\\\text{This is \textbf{equivalent}.}\\\\\text{This answer choice and the expression given has the same result when simplified.}$
