Weegy: Solution:
3x+6?15
First, let's work on the left hand side of your inequality, the 3x+6
This means, for instance, [ to see if it can be simplified at all.
Multiply x and 3
Multiply x and 1
The x just gets copied along.
The answer is x
x
3*x evaluates to 3x
3*x+6 evaluates to 3x+6
So, all-in-all, the left hand side of your inequality can be written as: 3x+6
Now, let's work on the right hand side of your inequality, the 15
The right hand side of your inequality can be written as: 15 So with these (any) simplifications, the inequality we'll set out to solve is:
3x+6 ? 15
Move the 6 to the right hand side by subtracting 6 from both sides, like this: From the left hand side:
6 - 6 = 0
The answer is 3x
From the right hand side:
15 - 6 = 9
The answer is 9
Now, the inequality reads:
3x ? 9
To isolate the x, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients)
around the x on the left side of the inequality.
The last step is to divide both sides of the inequality by 3 like this:
To divide x by 1
The x just gets copied along in the numerator.
The answer is x
3x ? 3 = x
9 ? 3 = 3
The solution to your inequality is:
x ? 3
So, your solution is:
x must be less than 3 ] bongche|Points 2153|
