答案：x=41 y=50
x+2=6 则x=4 150（x+12）=240x 则x=20 2x:3=6:5 则x=9/5 5y+8y=12 则y=1
x-2=6 则x=8 2x+3=x-1 则x=-4 6x-6=9x 则x=-2 8x-2=7x-2 则x=4
2x+4x=0 则x=0 3x-4+2x=4x-3 则x=1 7x-6=-5x 则x=3 2y=9 则y=2/9
x/2=x+6 则x=12 2.4x-9.8=1.4x-9 则x=0.8 x+9=18 则x=2 5/2+3y=5/2 则y=0
3x=63 则x=21 x/2+1=x 则x=2 4z+1=8z 则z=4 8+x+x=6 则x=-1

76x-66y=4082
30x-y=2940
