X>5
Since 2x>11-1 is 2x>10 divide by 2
And we get x>5
saveliy_v [14]3 years ago
8 0

Step-by-step explanation:

2x+1>11 <em>1</em><em> </em>is positive integers so it have to be cancelled by negative integer <em>1</em>

<em>2</em><em>x</em><em>></em><em>1</em><em>1</em><em>-</em><em>1</em><em> </em>

<em>2</em><em>x</em><em>></em><em>1</em><em>0</em><em> </em><em>two </em><em>will </em><em>be </em><em>cancelled</em><em> by</em><em> </em><em>two </em><em>to </em><em>get </em><em>x</em>

<em>then </em><em>we </em><em>divide </em><em>2</em><em> </em><em>from </em><em>1</em><em>0</em>

<em>x</em><em>></em><em>5</em><em> </em><em>this </em><em>means </em><em>x </em><em>is </em><em>greater </em><em>than </em><em>5</em><em> </em>

<em>{</em><em>x=</em><em>6</em><em>,</em><em>7</em><em>,</em><em>8</em><em>,</em><em>.</em><em>.</em><em>.</em><em>}</em>

Please help me now ! Thank you

First we'll do two basic steps. Step 1 is to subtract 18 from both sides. After that, divide both sides by 2 to get x^2 all by itself. Let's do those two steps now

2x^2+18 = 10
2x^2+18-18 = 10-18 <<--- step 1
2x^2 = -8
(2x^2)/2 = -8/2 <<--- step 2
x^2 = -4

At this point, it should be fairly clear there are no solutions. How can we tell? By remembering that x^2 is never negative as long as x is real. 

Using the rule that negative times negative is a positive value, it is impossible to square a real numbered value and get a negative result. 

For example
2^2 = 2*2 = 4
8^2 = 8*8 = 64
(-10)^2 = (-10)*(-10) = 100
(-14)^2 = (-14)*(-14) = 196

No matter what value we pick, the result is positive. The only exception is that 0^2 = 0 is neither positive nor negative.

So x^2 = -4 has no real solutions. Taking the square root of both sides leads to

x^2 = -4
sqrt(x^2) = sqrt(-4)
|x| = sqrt(4)*sqrt(-1)
|x| = 2*i
x = 2i or x = -2i
which are complex non-real values
