Question

Crammer's method
3x - 4y=10
4x +3y=5​

ans =

Answer 1

Step-by-step explanation:

3x-4y=10{multiplying whole equation by 3}

4x+3y=5{multiplying whole equation by 4}

So,

9x-12y=30................(i)

16x+12y=20..............(ii)

add equation i and ii,

12y can be cut by opposite charge

25x=50

x=2

On putting the value of x in equation ii
