I just worked this question. None of those are the answers
First we remove the brackets:
4x + 16 = 2x + 4
Group like terms:
4x - 2x = 4 - 16
Evaluate:
2x = -12
x = -12/2 = -6
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
Here, Add both the equations in order to eliminate y,
5x = 10
x = 10/5
x = 2
Now, substitute it in 1st equation,
8(2) - 4y = -32
-4y= -32- 16
y = -48/-4
y = 12
In short, Your Answer would be (2, 12)
Hope this helps!
Answer:
x=-15
Step-by-step explanation:
after we reduce multiply we get -15
X=(-4) or X= 4
add 112 to both sides
divide both sides by 7
then take the square root of 16
