The system of equations below has exactly one (x, y) pair for its solution.4x+6y=244x+6y=242x+y=82x+y=8If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.If we add the two equations in the original system, we have 6x+7y=326x+7y=32.

The length of the legs of this isosceles triangle is 19 meters.
What is a triangle?
A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know an isosceles triangle has two equal sides and their opposite angles are also equal.
Given, The leg of the isosceles triangle is two less than three times the length of its base.
Assuming the base to be x meter,
∴ The other two legs are (3x - 2).
The perimeter of the triangle is 45 m and we know it is the sum of the lengths of all the sides.
So, (3x - 2) + (3x - 2) + x = 45.
7x - 4 = 45.
7x = 49.
x = 7.
So, the length of the legs are (3.7 - 2) = 19 meters.

Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
