IALT: Solve an Algebra equation.

Malo E Lelei and welcome back to my blog! Today in Room 9 for Maths, I learned how to solve an Algebra equation.

I asked Mr Jay to give me ANY equation and to me I thought he was gonna ask, "34 x 14" or "128 x 6" But instead he said, "2x + 14 = 80" and my job was to find the value of the 'x'. On my first attempt to solve this equation, I divided 80÷14 and Mr Jay said to me that's incorrect. I was really confused so Mr Jay made it a bit easier and said, "Okay, the value of the 'x' is 33. Find out how." This made it a lot easier and I looked at the equation and said the x is 33 because 33 x 2 = 66 and 66 + 14 = 80!" I was really happy that I had found the answer and Mr Jay came and taught me how to write it. 

This is how you would write the answer to the equation:

There is supposed to be a dot/space between the 2 and 'x'. 

This looks like:

2.x

The dot means to multiply so basically you're multiplying the 2 by the 'x'.

2.x + 14 = 80

What we're first trying to do is get rid of the 14 so to get rid of the 14 we have to subtract 14 away from 14 which equals 0. 

(14-14=0)

Then we have to do the same with the 80. For example:

2x = 80 - 14

When Mr Jay explained how to solve this he always wrote '2x =' before he would continue. This looks like:

2x = 66

Which also means 80-14=66

Next you have to divide 66÷2 which is the number before the x. This should look like:

2x = 66÷2

And then the answer will be the value of the 'x'.

x = 33

Wait! We're not done yet. The 33 will the become the substitute of the 'x' and this will make the equation:

2.33 + 14 = 80

Because:

2x33=66

66+14=80

I am really glad I learned how to solve Algebra equations and I am very happy I was able to show Ako and teach Hevani and Grace how to solve these questions! One thing I need to work on is explaining WHY I have to always write 2x=, and WHAT does it do to the equation, but this just shows how much more I have to learn!

I can't wait to learn more about Algebra! I hope you have learned something!
