Решите уравнение:
a) 2+2/3+3-x/2=1
b) 4+x/4-x+6/3=-1
c) x-1/4+x-8/6=3
d) x+5/12-x+3/8=2

а) - x/2 = 1-2-3-2/3 x/2= 4×2/3 x=9×1/3b) x/4 - x= - 1 - 4 - 6/3 x/4 - x= - 5-2 x(1/4-1)= - 7 x= - 1/(-3/4) x= (1×4)/3 = 4/3c) x-1/4 +x - 8/6=3 2x= 3+1/4 + 8/6 2x=3+1/4+4/3 2x=3+(3+16)/12 2x = 36/12+19/12 2x = 55/12 x= 55/24=2×7/24d) x-x= 2-5/12-3/8 (48-10-9)/24=0 27/24=0 - ø
