1/4
are the numbers equivalent to 25%
Given:
The equation
goes through the coordinates (6,5) and (-2,-5).
To find:
The values of A and B.
Solution:
We have,
![Ax+By=10](https://tex.z-dn.net/?f=Ax%2BBy%3D10)
It goes through the coordinates (6,5) and (-2,-5). It means these points will satisfy the equation.
![A(6)+B(5)=10](https://tex.z-dn.net/?f=A%286%29%2BB%285%29%3D10)
...(i)
![A(-2)+B(-5)=10](https://tex.z-dn.net/?f=A%28-2%29%2BB%28-5%29%3D10)
...(ii)
Adding (i) and (ii), we get
![(6A+5B)+(-2A-5B)=10+10](https://tex.z-dn.net/?f=%286A%2B5B%29%2B%28-2A-5B%29%3D10%2B10)
![4A=20](https://tex.z-dn.net/?f=4A%3D20)
Divide both sides by 4.
![A=5](https://tex.z-dn.net/?f=A%3D5)
Put A=5 in (i), we get
Divide both sides by 5.
![B=-4](https://tex.z-dn.net/?f=B%3D-4)
Therefore, the values of A and B are 5 and -4 respectively.
