The sides of the equilateral are given in cm. 3x 2,2y-x,y 3. Find x and y and the perimeter of the triangle

Since all the sides are equal, we have

3x 2 = 2y-x
2y-x = y 3

Fix your typos and then solve for x and y. If I assume that your "+" key is not working, then we have

3x+2 = 2y-x
2y-x = y+3

(x,y) = (2,5)
So, the sides are 8 and p=24.

What if they ask you to look for the value of x only

Not clear

To find the values of x and y, we can set up a system of equations based on the given side lengths.

Let's label the sides of the equilateral triangle as a, b, and c, where:
a = 3x + 2
b = 2y - x
c = y + 3

Since it is an equilateral triangle, all three sides are equal. Therefore, we can equate any two sides to find the values of x and y.

Setting sides a and b equal, we have:
3x + 2 = 2y - x

Simplifying the equation, we have:
4x = 2y - 2

Divide by 2:
2x = y - 1

Setting sides b and c equal, we have:
2y - x = y + 3

Simplifying the equation, we have:
y - x = 3

Now we have a system of equations:
2x = y - 1
y - x = 3

From the second equation, we can isolate y:
y = x + 3

Substituting this value of y into the first equation:
2x = (x + 3) - 1

Simplifying the equation, we have:
2x = x + 2

Subtracting x from both sides:
x = 2

Now substituting the value of x back into the equation y = x + 3:
y = 2 + 3
y = 5

So, x = 2 and y = 5.

To find the perimeter of the equilateral triangle, we need to find the value of any side. Let's substitute x = 2 into side a:
a = 3x + 2
a = 3(2) + 2
a = 6 + 2
a = 8

Now we know that all sides are 8 cm. The perimeter (P) of an equilateral triangle is given by P = 3a (where a is the length of each side).

Plugging in the value of a:
P = 3(8)
P = 24 cm

Therefore, the perimeter of the equilateral triangle is 24 cm.
