\[
3(x-4)<2(2 x-1)
\]
Solution
Solution Steps
To solve the inequality \(3(x-4) < 2(2x-1)\), we need to follow these steps:
Distribute the constants on both sides of the inequality.
Combine like terms to isolate the variable \(x\) on one side.
Solve for \(x\).
Write the solution set in interval notation.
Step 1: Distribute the constants on both sides
First, we need to distribute the constants on both sides of the inequality:
\[
3(x - 4) < 2(2x - 1)
\]
Distribute the 3 on the left side:
\[
3x - 12
\]
Distribute the 2 on the right side:
\[
4x - 2
\]
So the inequality becomes:
\[
3x - 12 < 4x - 2
\]
Step 2: Move all terms involving \(x\) to one side
Next, we need to move all terms involving \(x\) to one side of the inequality. We can do this by subtracting \(3x\) from both sides:
\[
3x - 12 - 3x < 4x - 2 - 3x
\]
Simplify:
\[
-12 < x - 2
\]
Step 3: Isolate \(x\)
Now, we need to isolate \(x\) by adding 2 to both sides of the inequality:
\[
-12 + 2 < x - 2 + 2
\]
Simplify:
\[
-10 < x
\]
Step 4: Write the solution in interval notation
The inequality \(-10 < x\) can be written in interval notation as:
\[
(-10, \infty)
\]
