What value of x is in the solution set of 3 (x-4)> 5x+2
You solve this just like you would solve an equation. See the steps below.
3(x-4) > 5x+2
First Multiply 3(x-4). Multiply 3 by each number in the parentheses. First 3 * x then 3 * -4. That leaves you with 3x – 12. see below.
3x-12 > 5x+2
Next get the variables on the same side (of the > sign). Remember whatever you do to one side you need to do to the other side so we will subtract 5x from both sides.
3x -12 > 5x +2
That leaves us with..
-2x – 12 > 2
Now lets get the numbers on one side by adding 12 to both sides. Adding 12 to the side with -12 will get rid of the number from the left side and adding 12 to the right side makes it 14.
-2x – 12 > 2
That leaves us with…
-2x > 14
Now lets get x by itself by dividing by -2, again remember what we do to one side we need to do to the other.
-2x > 14
When you divide both sides by a negative number it reverses the sign from > to
x < -7
So the answer is any number less than -7, so -10 part of the solution set.
Hope this helped.
