Hey there!
We need to find the one value of x that, when plugged in, will equal 11.
You have asked if x can equal 5. Let's plug it in and see if it works.
3(5)+2=11
15+2=11
17=11
You can see that this statement is false. So, what can we do to find the right answer.
We need to isolate x so we can see what it equals. To do this, we will use inverse operations.
3x+2-2=11-2
3x=9
3x/3=9/3
x=3
If we plug in 3, you will see that it does equal 11, making the equation true.
I hope this helps!
