10) Solve the inequality for [tex]\(x\)[/tex]:

[tex]\[ \frac{1}{2}(x-2)\ \textgreater \ \frac{1}{4}(7x-2) \][/tex]


Sagot :

Certainly! Let's solve the inequality step-by-step:

Given the inequality:
[tex]\[ \frac{1}{2}(x-2) > \frac{1}{4}(7x-2) \][/tex]

### Step 1: Clear the Fractions
To eliminate the fractions, we can multiply both sides of the inequality by 4 (the least common multiple of the denominators 2 and 4):

[tex]\[ 4 \cdot \frac{1}{2}(x-2) > 4 \cdot \frac{1}{4}(7x-2) \][/tex]

This simplifies to:
[tex]\[ 2(x-2) > 7x-2 \][/tex]

### Step 2: Distribute the Constants
Next, we distribute the constants inside the parentheses:

[tex]\[ 2x - 4 > 7x - 2 \][/tex]

### Step 3: Arrange All Terms Involving [tex]\( x \)[/tex] on One Side
To isolate the [tex]\( x \)[/tex] terms on one side of the inequality, we can subtract [tex]\( 2x \)[/tex] from both sides:

[tex]\[ -4 > 5x - 2 \][/tex]

Next, add 2 to both sides to further isolate the [tex]\( x \)[/tex] term:

[tex]\[ -2 > 5x \][/tex]

### Step 4: Solve for [tex]\( x \)[/tex]
To solve for [tex]\( x \)[/tex], divide both sides by 5:

[tex]\[ \frac{-2}{5} > x \][/tex]

This can be rewritten as:

[tex]\[ x < \frac{-2}{5} \][/tex]

### Final Answer
Therefore, the solution to the inequality is:

[tex]\[ x < -0.4 \][/tex]

This inequality indicates that [tex]\( x \)[/tex] must be less than [tex]\(-0.4\)[/tex] to satisfy the given condition.
