Question

solve for x; √2x+√9+x=13​

Answer 1

Answer

8

Explaination:-

Given equ@tion is:

2x+9

+x=13 ... (i)

2x+9

=13−x

On squaring, we get

2x+9=x

2

+169−26x

⟹x

2

+160−28x=0

⟹x

2

−20x−8x+160=0

⟹(x−20)(x−8)=0

∴x=20 or x=8

But x=20 does not satisfy (i)

∴x=8 is the solution of (i)
