How do I find the value of x. The answer is 25/7 I just need to show the work.

Answer:
Below.
Step-by-step explanation:
As the 2 sides are both cut in half by the horizontal line, 7x-1 = 1/2 * the base line, so:
2(7x - 1) = 48
14x - 2 = 48
14x = 50
x = 50/14
= 25/7.
Answer:
x = [tex]\frac{25}{7}[/tex]
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
7x - 1 = [tex]\frac{1}{2}[/tex] × 48 = 24 ( add 1 to both sides )
7x = 25 ( divide both sides by 7 )
x = [tex]\frac{25}{7}[/tex]
