Solve 2x + 3/3 < 3x - 1/2

1 answer

To solve the inequality \( \frac{2x + 3}{3} < \frac{3x - 1}{2} \), we can start by eliminating the fractions. To do this, we find a common denominator, which in this case is 6.

Multiplying both sides by 6 gives:

\[ 6 \cdot \frac{2x + 3}{3} < 6 \cdot \frac{3x - 1}{2} \]

This simplifies to:

\[ 2(2x + 3) < 3(3x - 1) \]

Expanding both sides results in:

\[ 4x + 6 < 9x - 3 \]

Next, we will move the terms involving \( x \) to one side and the constant terms to the other side. Subtract \( 4x \) from both sides:

\[ 6 < 9x - 4x - 3 \]

This simplifies to:

\[ 6 < 5x - 3 \]

Next, add 3 to both sides:

\[ 6 + 3 < 5x \]

This results in:

\[ 9 < 5x \]

Now, divide both sides by 5:

\[ \frac{9}{5} < x \]

This is equivalent to:

\[ x > \frac{9}{5} \]

In interval notation, the solution is:

\[ \left( \frac{9}{5}, \infty \right) \]

Thus, the solution to the inequality \( \frac{2x + 3}{3} < \frac{3x - 1}{2} \) is \( x > \frac{9}{5} \).
