Please someone explain and give me ths answer

x = 10

Step-by-step explanation:

An isosceles triangle has two sides of equal length. In this triangle, there is a little line in the middle of two out of the three sides of the triangle. This line tells us that those two sides are equal. We know that the value of these sides are 4x - 8 and 2x + 12. So, to find the value of x, we can set the equations equal to each other and solve for x:

4x - 8 = 2x + 12

Subtract 2x from both sides to isolate x:

2x - 8 = 12

Add 8 to both sides:

2x = 20

Divide both sides of the equation by 2 to find the value of x:

x = 10

Hope this helps :)

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
