4+3xy=14x. or 14x-3xy=4.….(1)
3-4xy=23x or 23x+4xy=3....(2)
eq.(1) multiply by 4 and (2) by 3 than eq.(1)add eq. (2)
56x-12xy=16
69x+12xy=9
125x=25 or x= 1/5
x value put in eq. (1) than
14*1/5-3y/5=4
or 14-3y=20
or -3y= 20-14=6
or y=-6/3=-2
answer
x=1/5
y=-2
3-4xy=23x or 23x+4xy=3....(2)
eq.(1) multiply by 4 and (2) by 3 than eq.(1)add eq. (2)
56x-12xy=16
69x+12xy=9
125x=25 or x= 1/5
x value put in eq. (1) than
14*1/5-3y/5=4
or 14-3y=20
or -3y= 20-14=6
or y=-6/3=-2
answer
x=1/5
y=-2
