Hello!
I believe the number that can be written in the blank space above is 6.
48+54=6'(8+9)
The number written in the blank space is 6 because when you divide 48 and 54 by their numbers, 8 and 9, you will get an answer of 6 for both numbers.
48/8=6
54/9=6
So the number in the blank space would be 6.
I hope this helps!
8x+8y=2
-) 8x+5y=1
——————
3y=1
y=1/3
8x+8(1/3)=2
24x+8=6
24x=-2
x=-1/12
(-1/12,1/3)
