Question

3x + 2y =4. 8x +5y =9, then find the value of x anD y

Answer 1

3x+2y=4 let it is equation first
8x+5y=9 let it is equation second
Now, equation first multiply by 8and equation second multiply by 3 then,
24x+16y=32 equation four
24x+15y=27 equation fifth
Subtract equation fourth and fifth
Y=5
now put the value of x in equation first
3x+10=4
3x=-6
x=-2

Answer 2

3x+2y=4. ×5
8x+5y=9. ×2

15x+10y= 20
16x+10y= 18

-x= 2
x=-2
substitute x in eq 1
15x+10y= 20
15(-2)+10y= 20
-30+10y =20
10y= 20+30
y= 50/10
y= 5


I hope u got answer and this will help u
