Question

2x-3/4-1/3=-x+2/2


x-1/2+x-2/3=x-3/4


x-2/3-x+1/4=4​

Answer 1

Resposta:

2x-3/4-1/3=-x+2/2 mmc(3,4,2.1)=12

24x/12- 9/12 - 4/12=-12x +12/12 elimina os denominadores

24x-9 - 4=-12x+12

24x+12x=12+9+4

36x=25

x=25/36

x-1/2+x-2/3=x-3/4 mmc (2,3,4,1)=12

12x/12-6/12+12x/12-8/12=12x/12-9/12 elimina os denominadores

12x-6+12x-8=12x-9

12x+12x-12x =-9+6+8

12x=5

x=5/12

x-2/3-x+1/4=4 mmc (3,4,1)=12

12x/12-8/12+3/12=48/12 elimina os denominadores

12x-8+3=48

12x =48+8-3

12x =53

x=53/12
