Question

Determine o valor de X para que o ponto M (2,3) seja o ponto médio do segmento de extremos A(X,5) e B(3,X)​

Answer 1

$x_{M}=\dfrac{x_{A}+x_{B}}{2}\\2=\dfrac{x+3}{2}\\x+3=4\rightarrow\,x=4-3=1$

$y_{M}=\dfrac{y_{A}+y_{B}}{2}\\3=\dfrac{5+x}{2}\\x+5=6\rightarrow\,x=6-5=1$

Logo

$\boxed{\boxed{\mathsf{x=1}}}$
