Question

помогите решить СРОЧНО пожалуйста

Answer 1

х-1/3+х+1/4=4х-4+3х+3/12=7х-1/12

а/b+2/a=a'2+2b/ab

2t/xy+3x/yt=2t'2+3x'2/txy

x+y'2-x'2+y'2/x+y=(x-y)(x+y'2)-x'2+y'2/x-y=y'2-y'3+xy'2-yx/x-y

y-27/6-2y+4y/3-y=y-27/2(3-y)+4y/3-y=9y-27/2(3-y)=-9(3-y)/2(3-y)=-4.5

c+5/3+2c+9/8=14c+67/24

3/y-y'2/x=3x-y'3/xy

6s/pq+8p/qs=6s'2+8p'2/pqs

x-y-x'2+y'2/x-y=x'2-2xy+y'2-x'2+y'2/x-y=2y'2-2xy/x-y

c-2/6c+4-4y/15c+10=c-2/2(3c+2)-4y/5(3c+2)=5c-10-8y/10(3c+2)
