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?
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?
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.
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
let's bring 14 to the other side|dw:1433264601534:dw|
what do you get now?
Im still sorta confused and im just gonna guess
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?
Kinda... I asked my sister for help and shes explaining it to me now. Thanks for the help anyway c:
