pls help me with this

Answer:
x = [tex]\frac{52}{7}[/tex]
Step-by-step explanation:
simplify right side of the equation
[tex]\frac{26}{x}[/tex] = 3.5 = [tex]\frac{7}{2}[/tex] (cross- multiply )
26 = [tex]\frac{7}{2}[/tex] x
multiply both sides by 2
52 = 7x ( divide both sides by 7 )
x = [tex]\frac{52}{7}[/tex] ← exact value
