VashaNatasha [74]

Answer:

The number of goats in the farm is $74$

The number of sheep in the farm is $63$

Step-by-step explanation:

Let

x----> the number of goats in the farm

y----> the number of sheep

we know that

$x+y=137$ ----> equation A

$x=y+11$ -----> equation B

substitute the equation B in equation A and solve for y

$(y+11)+y=137$

$2y=137-11$

$2y=126$

$y=126/2=63$

Find the value of x

$x=63+11=74$

therefore

The number of goats in the farm is $74$

The number of sheep in the farm is $63$
