Transcript text: What is the solution set for the following inequality?
\[
4 x-3+6 x>5 x+7
\]
$x<2$
$x>0.8$
$x>2$
$x<0.8$
Solution
Solution Steps
Step 1: Combine like terms to get the inequality into the form \(ax + b > cx + d\)
This step involves conceptual understanding of the problem form and does not require calculation.
Step 2: Subtract \(cx\) and \(d\) from both sides to get \(ax - cx > d - b\)
This simplifies the inequality by moving all terms involving \(x\) to one side and constants to the other.
Step 3: Simplify the inequality to \(x(a - c) > d - b\)
This step involves simplifying the inequality to isolate \(x\).
Step 4: Solve for \(x\) by dividing both sides by \(a - c\), resulting in \(x > \frac{d - b}{a - c}\) if \(a - c > 0\), or \(x < \frac{d - b}{a - c}\) if \(a - c < 0\).
If \(a - c = 0\), the inequality simplifies to a comparison of constants, which may result in a trivial truth or falsehood.
