Question

If root 2x+9+x=13 then the value of x is NOTE IT IS ANSWER 8 OR 20 BUT DO NOT KNOW HOW TO DO IT SO PLEASE GIVE THE ANSWER

Answer 1

Answer:

Given: √2x+9+x=13

So, squaring on both sides,

2x+9+x=169

3x+9=169

x=(169-9)/3=160/3=53.333333333

But I assume you made a typo and it is √2x²+9+x=13

So, squaring on both sides,

2x²+x+9=169

2x²+x-160=0

x= (-1-√1281)/4=-9.198

x= (-1+√1281)/4=8.698

OR

If this question was wrong, I assume √x²+2x+9=13

So, again squaring on both sides,

x²+2x+9=169

x²+2x-160=0

x= (-2-√644)/2=−13.689

x= (-2+√644)/2=11.689
