D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17
hopes it helps:)
Answer:
B. 5/9 I TOOK THE TEST
Step-by-step explanation:
Answer: First option.
Step-by-step explanation:
Given the following equation provided in the exercise:
![\sqrt[3]{x+8}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B8%7D%3D-4)
You can follow the steps indicated below in order to find the solution of this equation:
1. Cubing both sides of the equation, you get:
![(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%2B8%7D%29%5E3%3D%28-4%29%5E3%5C%5C%5C%5Cx%2B8%3D-64)
2. Finally you must subtract 8 from both sides of the equation:

You can notice that this solution matches with the first option.
