25 is a perfect cube I believe
Answer:
x = 0
Step-by-step explanation:
The goal is to isolate x. For this equation, you need to distribute the -3 to the terms inside the parentheses first. Then, add both sides by 12. Finally, divide the 24 by -3 in order to finally isolate x.
![-3 (x + 4) = 12\\-3x - 12 = 12 \\-3x = 24\\x = - 8](https://tex.z-dn.net/?f=-3%20%28x%20%2B%204%29%20%3D%2012%5C%5C-3x%20-%2012%20%3D%2012%20%5C%5C-3x%20%3D%2024%5C%5Cx%20%3D%20-%208)
Thus, x = -8.
Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
