Good morning Brainiac

x+y = 13

1/2 x +y = 10


We gonna solve x+y=13 for x

So let's start by adding -y to both sides

x+y -y = 13-y

x= -y +13

Now substitute -y+13 for x in 1/2 x +y=10

1/2 x +y = 10

1/2 (-y+13)+y=10

1/2 y + 13/2 = 10

Now add -13/2 to both sides

1/2 y+13/2 -13/2 = 10- 13/2

1/2 y = 7/2

Now eliminate the common denominator which is 2

y = 7

Now we have the value for y, so lets find the value for x by substitute 7 for y in x= -y+13

x= -y+13

x= -7 + 13

x= 6

Answer : (6,7)

The answer is B


I hope that's help and if you have questions please let me know :)
