I have been struggling to try to solve this for over 4 days now and have had no luck. We are given the final answer which is (5,10) but I can not figurge out how they got to that. I need to show the work and solve the problem. Can someone please help me.
You can put this solution on YOUR website! while writing the problem it is advisable to put brackets to get clarity.
x/4+3y=31 ...............1
2x-y/5=8 ................2
...
multiply by 4
4*x/4 +4*3y= 31*4
x+12y=124...........3
..
2x- y/5 =8
multiply by 5
5*2x-5*y/5= 5*8
10x-y= 40.............4
..
..
multiply equation 3 by -10 and to equation 4
-10x-120y+10x-y=-1240+40
-121y=-1200
y= 1200/121
plug the value of y in the above equation
x=604/121
