2) 5y+15=57-2y

3) 7y-23=2y+32

4) 4y/5-7=13

5) 9y-12=24+3y

son ecuaciones

ayudenme porfa

Answer 1

1) 3y/4+9=20
3y/13+9=20
3y/18=20
6y=20
y=20/6


2) 5y+15=57-2y
5y+2y=57-15
7y= 42
y=42/7
y= 6


3) 7y-23=2y+32
7y-2y=23+32
5y = 55
y=55/5
y=11


4)4y/5-7=13
4y/-2=13
-2y=13
y= 13/-2


5) 9y-12=24+3y
9y-3y=12+24
3y=36
y=36/3
y=12
