Step-by-step explanation:

दिए गए बिंदु L (x, 7) तथा M (1, 15)

 x_{1} = x \\  y_{1} = 7 \\ x_{2} = 1 \\  y_{2} = 15

बिंदुओं के बीच की दूरी = 10 मात्रक

दूरी सूत्र के द्वारा,

दो बिंदुओं के बीच की दूरी=  \sqrt{ {( x_{2} - x_{1} )}^{2}  +    {( y_{2} - y_{1} )}^{2}}  \\  10=  \sqrt{ ({1 - x})^{2}  +  ({15 - 7})^{2} }    \\ on \: squaring \: both \: sides \\  {10}^{2}  = { ({1 - x})^{2}  +  ({15 - 7})^{2}} \\  {10}^{2}  =  {(1 - x)}^{2}  +  {8}^{2}  \\ 100 = {(1 - x)}^{2} + 64 \\ 100 - 64 = {(1 - x)}^{2} \\ 36 = {(1 - x)}^{2} \\  {6}^{2}  = {(1 - x)}^{2} \\ on \: comparing \\ 1 - x = 6 \\  - x = 6 - 1 \\  - x = 5 \\  - x \times  - 1 = 5 \times  - 1 \\ x =  - 5
