Question

Resuelve
*3/2 m= 5/7
*3,5 X +2 =5,5
*0,2 X +1 =9
*1/4 + X = 17/20
*2/7 X -9/4 = 5/3
*Y + 3/4 = 1/5


.

Answer 1

*m=(5/7)/(3/2)
m=10/21
m=0,48

*3,5x+2=5,5
3,5x=3,5x
x=1

*0,2x+1=9
x=8/0,2
x=40

*1/4+x=17/20
x/4=17/20
20x=68
x=17/5

*2/7x-9/4=5/3
2x/7-9/4=5/3
24x-189=140
24x=329
x=24/329
x=13,71

*y=1/5-3/4
y=-9/20
y=-0,45
