Solving Systems of Linear Equations by Multiplication and Addition Method
...s in both equations, the same.
Multiplying the equations
So let us multiply equation (2) by 2. We get
8x + 10y = -14......(3) [equation 2 is multiplied by 2 on the left and right hand side]
Now multiply equation (1) by -1. We get
- 8x - 3y = 21......(4) [equation 1 is multiplied by 2 on the left and right hand side]
Adding the equations for eliminating 'x'
Now add ...
