Sagot :
Answer:
13
Step-by-step explanation:
Mean would mean average, which in this case is [tex]\frac{x+y}{2}[/tex]
so your equation would look like [tex]\frac{69+x}{2}=41[/tex]
Next multiply both sides by to clear the fraction [tex]2*(\frac{69+x}{2})[/tex]
to get [tex]69+x=89[/tex]
Subtract 69 from both sides [tex]69+x=82\\-69 -69[/tex]
you get [tex]x = 13[/tex]
