Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.
Im trying to find it too, i said 12,10.5 and 15,11 but im not sure..

Step-by-step explanation:
Stick change flip
5/6 x 10/3 = 50/18 2 14/18 simplify 2 7/9
Solve (x) F(x)=x^2+3x-2 is x-2
