Step-by-step explanation:
It's the Last one, because, shift means your going to move up and it's positive 1
Y - 5 = 3 - 9(y + 2)
Expand the brackets
y - 5 = 3 - 9y + 18
Move y to one side, and constants to the other
10y = 26
Solve for y
y = (26 / 10) = 2.6
Answer:
Correct option is A
Since it is an equilateral triangle, the lengths of the sides are equal
So, x+3 y=3 x+2 y−2=4 x+

y+1
x+3 y=3 x+2 y−2
y=2 x−2
2 x−y=2 ...(1)
Also, 4 x+

y+1=x+3 y
8 x+y+2=2 x+6 y
6 x+2=5 y
6 x−5 y=−2 ...(2)
Multiplying e q(1) by 5 we get,
10 x−5 y=10 ...(3)
Subtracting e q(2) from e q(3) we get,
4 x=12⇒x=3
y=2 x−2=4
The length of one side of equilateral triangle = x+3 y =3+3(4)=15 units
