hola!!

r= 1/2

s= 1/3

t= 1/6

Explicación paso a paso:

2r + 3s + 12t = 4

4r - 6s + 6t = 1

r + s + t = 1

2r + 3s + 12t = 4

r + s + t = 1

4r - 6s + 6t = 1

r + s + t = 1

s + 10t = 2

4r - 6s + 6t = 1

r + s + t = 1

s + 10t = 2

 - 10s + 2t =  - 3

s + 10t = 2

 - 10s + 2t =  - 3

s =  \frac{1}{3}

t =  \frac{1}{6}

r  + \frac{1}{2}  +  \frac{1}{6}  = 1

r =  \frac{1}{2}

comprobacion:

2 \times  \frac{1}{2} + 3 \times  \frac{1}{3} + 12 \times  \frac{1}{6} = 4

4 \times  \frac{1}{2} - 6 \times  \frac{1}{3} + 6 \times  \frac{1}{6} = 1

 \frac{1}{2} +  \frac{1}{3}  +  \frac{1}{6} = 1

4 = 4

1 = 1

1 = 1
