Answer 2

Answer:

The value of x is 7 and the value of y is 1.

Step-by-step explanation:

Given information: In an equilateral triangle ABC, AB= (3X + 1 ) cm, BC=(2x + 3y + 5)cm, and AC= ( x+9y+6)cm.

We need to find the value of x is y.

All sides of an equilateral triangle are congruent.

AB=BCAB=BC

3x+1=2x+3y+53x+1=2x+3y+5

x-3y=4x−3y=4 .... (1)

AB=ACAB=AC

3x+1=x+9y+63x+1=x+9y+6

2x-9y=52x−9y=5 .... (2)

Multiply equation (1) by 3 and subtract from equation (2).

2x-9y-3(x-3y)=5-3(4)2x−9y−3(x−3y)=5−3(4)

2x-9y-3x+9y=5-122x−9y−3x+9y=5−12

-x=-7−x=−7

x=7x=7

Substitute x=7 in equation (1).

(7)-3y=4(7)−3y=4

-3y=4-7−3y=4−7

-3y=-3−3y=−3

y=1y=1

Therefore, the value of x is 7 and the value of y is 1.
