Give the solution for the following inequality:

[tex]\[ x - 4 \ \textgreater \ 4(x - 1) \][/tex]


Sagot :

To solve the inequality [tex]\(x - 4 > 4(x - 1)\)[/tex], follow these steps:

1. Expand and Simplify:
First, distribute the 4 on the right-hand side:
[tex]\[ x - 4 > 4(x - 1) \implies x - 4 > 4x - 4 \cdot 1 \implies x - 4 > 4x - 4 \][/tex]

2. Combine Like Terms:
Next, we need to collect all [tex]\(x\)[/tex]-terms on one side and constants on the other side. Start by subtracting [tex]\(x\)[/tex] from both sides:
[tex]\[ x - 4 - x > 4x - x - 4 \implies -4 > 3x - 4 \][/tex]

Then, add 4 to both sides:
[tex]\[ -4 + 4 > 3x - 4 + 4 \implies 0 > 3x \][/tex]

3. Isolate [tex]\(x\)[/tex]:
Finally, divide both sides by 3 to solve for [tex]\(x\)[/tex]:
[tex]\[ 0 > 3x \implies 0 > x \][/tex]
Rewriting this, we get:
[tex]\[ x < 0 \][/tex]

The solution to the inequality [tex]\(x - 4 > 4(x - 1)\)[/tex] is:
[tex]\[ x < 0 \][/tex]

In interval notation, the solution is:
[tex]\[ (-\infty, 0) \][/tex]
