1) 6y - 3 = 3 + 2y 2) 9 - 10z = 5 - 9z 3) 12x - 7 = 2x - 16

Question

1) 6y - 3 = 3 + 2y
2) 9 - 10z = 5 - 9z
3) 12x - 7 = 2x - 16

Answer 1

1) 6у-3=3+2у
    6у-2у=3+3
    4у=6
    у=6/4
    у=1.5
2) 9-10z=5-9z
    -9z+10z=9-5
    z=4
3) 12x-7=2x-16
    12x-2x=-16+7
    10x=-9
     x=-9/10
     x=-0/9
