What is the value of x in the linear inequality ?<br> -3(4x-8.2)&lt;-11.98x+14 3/4
Karo-lina-s [1.5K]

Solving the inequality -3(4x-8.2) we get value of x: x>492.5

Step-by-step explanation:

We need to solve the inequality -3(4x-8.2) and find value of x.

Solving:

-3(4x-8.2)

Multiplying -3 with the terms inside the bracket

-12x+24.6

Converting mixed fraction into improper fraction:

-12x+24.6

Adding 11.98x on both sides

-12x+24.6+11.98x

Subtracting 24.6 on both sides:

-0.02x+24.6-24.6

Divide both sides by -0.02 and reverse the inequality i.e < sign is changed to > due to division of (-) sign.

\frac{-0.02x}{-0.02}492.5

So, solving the inequality -3(4x-8.2) we get value of x: x>492.5
