The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.
What is an equilateral triangle?
An equilateral triangle is a triangle that has all its sides equal to each other.
Therefore,
3x - 5 = 5y - 4 (equilateral triangle)
3x - 5y = 1
Therefore,
y + 12 = 3x - 5 (Isosceles triangle)
y - 3x = - 17
Hence,
3x - 5y = 1
- 3x + y = - 17
-4y = -16
y = -16 / -4
y = 4
Therefore,
3x = 1 + 5(4)
3x = 21
x = 21 / 3
x = 7
