Answer:


x < -3(3)/(4)

Explanation:

Given


-6x+22(1)/(4)+2x &amp;gt; 9(3)/(4) +16(1)/(2)

Required

Solve for x


-6x+22(1)/(4)+2x &amp;gt; 9(3)/(4) +16(1)/(2)

Collect Like Terms


-6x+2x &amp;gt; 9(3)/(4) +16(1)/(2)-22(1)/(4)


-4x &amp;gt; 9(3)/(4) +16(1)/(2)-22(1)/(4)

Convert all fractions to improper fractions


-4x &amp;gt; (39)/(4) +(33)/(2)-(45)/(4)

Take LCM


-4x &amp;gt; (39+66- 45)/(4)


-4x &amp;gt; (60)/(4)


-4x &amp;gt; 15

Divide through by -4; When an inequality is divided by a negative number, the inequality changes.


(-4x)/(-4) &amp;lt; (15)/(-4)


x &amp;lt; (15)/(-4)


x &amp;lt; -(15)/(4)

Convert to improper fraction


x < -3(3)/(4)
