Answer 2

The correct answer will be "x=$\frac{4}{3}$". Further explanation is given below.

Step-by-step explanation:

Given equation is:

(x+4)²-(x-5)²=15

On solving the above equation, we get

⇒ x²+16+8x-(x²+25-10x)=15

⇒ x²+16+8x-x²-25+10x=15

⇒ 16+8x-25+10x=15

⇒ -9+18x=15

⇒ -9-15+18x=0

⇒ -24+18x=0

⇒        18x=24

⇒            x=$\frac{24}{18}$

⇒            x=$\frac{4}{3}$
