ANSWER

$-32$

EXPLANATION

We want to solve the given expression for x = -18:

$\frac{5x}{3}-2$

To do this, substitute the given value of x into the expression and simplify. That is:

$\begin{gathered} \frac{5(-18)}{3}-2 \\ \frac{-90}{3}-2 \\ -30-2 \\ \Rightarrow-32 \end{gathered}$

That is the answer.

4 people went to the movies. Each person spent $9.50 on a ticket and had the same amount of money leftover. They originally had

solong [7]

$2.50 was left for each person.

4(9.50) + x = 48

38 + x = 48

subtract 38 on both sides

x = 10

10$ was left in total by all 4 people

10/4 = 2.50

$2.50 was left over for each person
