Answer:
x = 7
Step-by-step explanation:
An isosceles triangle has two equal sides, if ∠S is the vertex, then SO and ST have the same length. Then,
SO = ST
3x = 5x - 14
Now, we can solve the equation for x.
Add 14 to both sides
3x + 14 = 5x - 14 + 14
3x + 14 = 5x
Subtract 3x from both sides
3x + 14 - 3x = 5x - 3x
14 = 2x
Finally, divide both sides by 2
14/2 = 2x/2
7 = x
Therefore, the value of x is 7.
