It's an equilateral triangle. that is, all the sides are equal
So, 9x-14=7x
can you find out x from this equation?

Im really bad at this and I dont really know how to figure it ou but down I add or subtract 14 from both sides now?

- anonymous

I wasnt really sure how to do this so I just subtracted 23-9 and got 14 so I was just guessing maybe it was right.

- Diyadiya

Its okay :D i'll try to help you!
9x-14=7x
you have to bring all the terms with variable x on one side and constants on another side

- Diyadiya

let's bring 14 to the other side|dw:1433264601534:dw|

- Diyadiya

what do you get now?

- anonymous

Im still sorta confused and im just gonna guess

- Diyadiya

you have to bring all the terms with variable 'x' (9x & 7x) on one side and constants (14) on another side.
that's how we solve such equations with one variable.
do you understand this part?
