Question

encontrar el valor de x en
X ( N-M )+N ( X+M )=2M ( 2N-X )

Answer 1

Cordial saludo.

X(N-M)+N(X+M)=2M(2N-X)

NX-MX+NX+MN= 4MN-2MX

2NX+MX = 3MN

X(2N+M)=3MN

X=3MN/(2N+M)

Un abrazo de Mastertareascolombia.

Answer 2

Multiplica lo del paréntesis
XN-XM+NX+NM=4MN-2MX
Reduce términos semejantes
2XN+2MX-XM=4MN-NM
2XN+MX=3MN
Factoriza "x"
X(2N+M)=3MN
X=3MN/(2N+M)
