Question

Rozwiąż równanie:
3(y+2)=5
(y+3)=5y+2+2y
1/2y + 1/3= 7/6

Answer 1

3y+6=5 | -6
3y= -1 | :3
y =0,33

(y+3)=5y+2+2y |-3
y=7y -1 | -7y
-6y=-1 |: (-6)
y=0,16

1/2y+1/3=7/6
1/2y+2/6=7/6 | - 2/6
1/2y=5/6 | : 1/2
y=1 4/6

Answer 2

3(y+2)=5
3y+6=5
3y=-1
y=-1/3


(y+3)=5y+2+2y
6y=1
y=1/6


1/2y+1/3=7/6
1/2y=5/6
y=10/6
y=1 2/3

Answer 3

1) 3(y+2)=5
3y+6=5
3y=5-6
3y=-1 |:3

to już sobie dolicz :p

2) (y+3)=5y+2+2y
y+3=5y+2+2y
y-5y-2y=2-3
-6y=-1 |:(-6)
to też policz ;p

1/2y+1/3=7/6
1/2y=7/6-1/3
1/2y=7/6-2/6
1/2y=5/6
