134

This is because 
And 
For this reason, 
Positive indices mean we have to multiply the same number twice or thrice based on the value of the index. On the other hand, negative indices mean we have to divide by the same number twice or thrice based on the value of the index.
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)
