3x+5y= -9 (i)
2x+y=-34 (ii)
Now, multiplying (ii) from 5, we get,
3x+5y=-9
10x+5y=-34 (iii)
Now, On subtracting eq. (i) from (iii)
10x+5y=-34
3x+5y=-9
7x=-25
x=-25/7
On substituting the value of x in eq. (ii)
2×-25/7±y=-34
y=-34+50/7
y=-188/7
2x+y=-34 (ii)
Now, multiplying (ii) from 5, we get,
3x+5y=-9
10x+5y=-34 (iii)
Now, On subtracting eq. (i) from (iii)
10x+5y=-34
3x+5y=-9
7x=-25
x=-25/7
On substituting the value of x in eq. (ii)
2×-25/7±y=-34
y=-34+50/7
y=-188/7
