Question

Calculati : mx-2x+3=x(2m-3)+m+2 ​

Answer 1

Răspuns:

$x=\frac{1}{m} \\\\m=\frac{1}{x}$

Explicație pas cu pas:

$mx-2x+3=x(2m-3)+m+2\\mx-2x+3=2x(xm)-3+m+2\\mx-2x+3=3xm-3+m+2|-2\\mx-2x+1=3xm-3+m|+3\\mx-2x+4=3xm+m|+2x\\mx+4=5x2m|:mx\\4=4xm\\4xm=4|:4\\xm=1|:x\\\\m=\frac{1}{x}\\\\y=\frac{1}{m}$

$m=x^-^1\\x=m^-^1$

Succes! :)
