Verified answer

2v/(x² + 2xv) = 2v/x(x + 2v)

v/(xt - 5x²) = v/x(t - 5x)

(t + 10v)/(xt + 2vt - 10xv - 5x²) = (t + 10v)/(x + 2v)(t - 5x)

общий знаменатель x(x + 2v)(t - 5x)

2v/x(x + 2v) = 2v(t - 5x)/x(x + 2v)(t - 5x) = (2vt - 10vx)/x(x + 2v)(t - 5x)

v/x(t - 5x) =  v(x + 2v)/x(t - 5x)(x + 2v) = (vx + 2v²)/x(t - 5x)(x + 2v)

(t + 10v)/(x + 2v)(t - 5x) = x(t + 10v)/(x + 2v)(t - 5x)x = (xt + 10xv)/(x + 2v)(t - 5x)x
