When you get to “c“ or the last number you add
The answer that seems to make the most sense is 0.27
Hello!
3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
There are an infinite number of them.
Here are a few:
2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.
How to find them:
You probably never heard this before, but I'll bet
you'll remember it from now on:
<em>ANY number that you can write down on paper completely, </em><em>using digits
and a decimal point if you need it but no symbols, is a rational number.</em>
If you can write it down completely without any 'comments', then it's rational.
