What is the solution set? Enter your answer in the box

Xelga [282]

Answer:

$x>3$

The solution set is $(3, infinite)$

Step-by-step explanation:

we have

$5.5x+15.5>32$

Solve for x

Subtract $15.5$ both sides

$5.5x+15.5-15.5>32-15.5$

$5.5x>16.5$

Divide by $5.5$ both sides

$5.5x/5.5>16.5/5.5$

$x>3$

The solution is the interval-------> $(3, infinite)$

All real numbers greater than $3$
