Question

3x+5y=12 and 5x+3y=4 then the value of x and y​

Answer 1

3x+5y=12----(1)
5x+3y=4-----(2)

mutiplying equation no. 1 by 2 and equation no.2 by 5
9x+15y=36-------(3)
25x+15y=20-----(4)

subtracting equation no.3 from 4
16x=-16
x=-16/16
x=-1

put x=-1 in equation no. 1
3x+5y=12
3×-1+5y=12
-3+5y=12
5y=12+3
5y=15
y=15/5
y=3

(x,y)=(-1,3) is the soln of ur question
