Question

Suppose two sides of an equilateral triangle are represented by 5y - 6 and 4y + 12. What is the value of y?

Answer 1

Equilateral means the sides are the same size. That means you can put those two equations equal to each other.

4y + 12 = 5y - 6
18 = y

Answer 2

5y-6=4y+12

Answer 3

So whats the value of Y?

Answer 4

y= 18
