Can someone please check this? I think the answer is 23.

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

anonymous · Answer

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 · Answer

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 · Answer

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 · Answer

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