X+4x=35-20. 5x=35-20. 5x=15. X=3
Answer:
4.33
Step-by-step explanation:
If you don't have the cube root function in your calculator, u can chose a choice instead and cube the value.
9x9 is already 81, hence 9x9x9 > 81
27 x 27 Is definitely more than 81
Hence the only reasonable answer is 4.33
You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
![x^{2} - 4 [(x-4)^{2}] =16 ](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-%204%20%5B%28x-4%29%5E%7B2%7D%5D%20%3D16%0A%20)
expand, collect like terms, factor to find x, then plug x value back into original equation to find y
