Question

30% x y + y = 52

Answer 1

30% x y + y = 52

( 3/10 x y ) + y = 52

13/10 x y = 52

            y = 52 : 13/10

            y = 40

Answer 2

30% x y + y = 52

y x 130% = 52

y = 52 : 130% = 40

      Đáp số: 40

Answer 3

40 chắc 100%

Answer 4

30%*y+y=52

3/10*y+y*1=52

y*(3/10+1)=52

y*13/10=52

y         =52:13/10

y         =40

Answer 5

30% x y + y = 52

y x 130% = 52

y = 52 : 130% = 40

      Đáp số: 40
