Question

What is the value of x?


Enter your answer in the box.

x =

Answer 1

Answer: x = 3

Explanation:

This is an equilateral triangle, all the angles are congruence so also all the sides are equal, therefore you can equate any of the side to the other

6x - 3 = 5x

collect like term

6x-5x = 3

x = 3

OR

3x + 6 = 5x

5x - 3x = 6

2x = 6

divide bothside by 2

x= 3

OR

6x-3 = 3x + 6

collect like term

6x - 3x = 6 + 3

3x = 9

Divide bothside by 3

x = 3

Therefore x= 3

Answer 2

Since this is an equilateral triangle , all three sides are the same length

6x-3 = 5x = 3x+6

6x-3 = 5x

subtract 6x from each side

6x-3-6x = 5x -6x

-3 = -x

divide by -1

x=3
