What is the way to find the answer to the problem....3x+1=10?
My teacher told us in class but I just didn't understad it.
The idea is to get the x all alone on one side.
Subtract one from each side.
Then, divide each side by three.
3x + 1 = 10
First subtract 1 from both sides. That should get you started.
OK HERE GOES>>>>
3x + 1 = 10.
So three of something, plus one equals ten in otherwords. I take away the one first. So now you have
3x = 9
Now what number three times equals nine?
Well that would be three !
So
3x = 9
means that
x = 3.
and your solution
3x = 1 = 10
Means
that three of x (which is three 3 times so that's nine to check)
plus 1 equals ten.
AKA X = 3.
If you need help from your teacher again, don't be afraid to ask. Keep asking until you understand.
sorry if i confused you. sometimes
algebra looks hard, but indeed is very simple. The hardest part is understanding how it is so simple !
Good Luck =)
