Question

1. Solve the pair of linear equations by elimination method :
4x - 3y - 25 = 0 ; 3x + 4y - 25 = 0
​

Answer 1

Step-by-step explanation:

1. ( 4x-3y +4x+3y )
2. +25-25=0
3. 4x+4x
4. -3y+3y
5. 8x=-4+25/25
6. 8x=-4=0

Answer 2

Answer:

The elimination method is where you actually eliminate one of the variables by adding the two equations. In this way, you eliminate one variable so you can solve for the other variable. In a two-equation system, since you have two variables, eliminating one makes the process of solving for the other quite easy

7x - y - 50= 0
