Explanation / Answer

Given system of linear equation is

3x+5y=2 ............1)

4x-3y=22 ............2)

multiply equation 1) by 3 and equation by 5

we get,

9x+15y=6..........3)

20x-15y=110........4)

Add equation 3 and 4.

9x+15y=6..........3)

+ 20x-15y=110........4)

........................................

29x=116

x=116/29

x=4

put x=4 in equation (1)

3*4+5y=2

12+5y=2

5y=2-12

5y=-10

y=-2

hence the solution set is (4,-2)
