1)x+7/12=3/4 х = 3/4-7/12х = 9/12-7/12х = 2/12 = 1/62)x-1/6=1/9х = 1/9+1/6х = 2/18+3/18х = 5/183)x-3/5=3/8х = 3/8+3/5х = 15/40+24/40х = 39/404)x+5/24=7/12х = 7/12-5/24х = 14/24-5/24х = 9/24 = 3/85)y+2/7=1/3у = 1/3-2/7у = 7/21-6/21у = 1/216)x-1/6=7/9х = 7/9+1/6 х = 14/18+3/18 х = 17/187)y-3/8=5/32у =5/32+3/8у = 5/32+12/32у = 17/328)y+2/5=1/2у = 1/2-2/5у = 5/10-4/10у = 1/10 = 0.1...
