The value of x for the given equation (x + 50)/2 = 13x is 2.
According to the given question.
We have an equation (x + 50)/2 = 13x, which represents when two tutoring services with different rate plans charge the same fees for a session of x hours.
So, we have to solve the given equation (x + 50)/2 = 13x for x.
Therefore,
x + 50 = 2(13x)
⇒ x + 50 = 26x
⇒ 26x - x = 50
⇒ 25x = 50
⇒ x = 50/25
⇒ x = 2
Hence, the value of x for the given equation (x + 50)/2 = 13x is 2.
