11 votes

Step-by-step explanation:

  • Given the Inequality.


3x + 3 > 48

  • Solving the Inequality is similar to solving the equation. We simply make x-term as the subject since we are solving for x.


3x > 48 - 3 \\ 3x > 45 \\ x > (45)/(3) \Longrightarrow x > \frac{ \cancel{45}}{ \cancel{3}} \Longrightarrow x > (15)/(1) \\ x > 15

  • Answer Check

Because x must be greater than 15. We will substitute x = 16 in the Inequality.


3(16) + 3 > 48 \\ 48 + 3 > 48 \\ 51 > 48 \: \: \checkmark

The Inequality is true when x > 15.

Answer


\large \boxed{x > 15}
