Question

1. 5y + 1(per)4 = 4y - 1(per)2
2. x - 1 1(per)2 =2 1(per)3
Tolong yaa, makasih :)

Answer 1

1. 5y + 1/4 = 4y - 1/2
   5y - 4y    = -1/2 -1/4
         y      = -3/4
2. x - 3/2 = 7/3
       x     = 7/3 + 3/2
       x     = 23/6
       x     = 3 5/6
semoga membantu :)

Answer 2

5y+¼ =4y-½
5y-4y= -¼-½
1y= -¼-2/4
1y=3/4
y=3/4/1
y= 1 x 4/3
y=4/3
y= 1,33
