So Confused!! Somebody Plz Explain How To Do!!!!!!!
Anton [14]

Answer:   A) 3x + 5x - 4 = 1

<u>Step-by-step explanation:</u>

The second equation is y + 4 = 5x.  Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4

Now replace "y" in the first equation with "5x - 4".

     3x +      y     = 1

-->  3x + (5x - 4) = 1

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • To solve for 'x', we would have to use inverse operations.
  • We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
  • We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

What does B equal to
inna [77]
( the answer is 15) because in a equilateral all angles are equal and in the right triangle you already have 1 angle so just divide by 2 you get 45 so subtract 45 from 60
