Question

tìm x biết 10/3 nhân 1/2 - (1/2 nhân x trừ 1/3) + 1/5=3/5 : 1/2

Answer 1

10/3 x 1/2 - ( 1/2 x X - 1/3) + 1/5 = 3/5 :1/2

5/3 - ( 1/2 x X - 1/3) + 1/5 = 6/5

5/3 - ( 1/2 x X - 1/3) = 6/5 + 1/5

5/3 - ( 1/2 x X - 1/3) = 7/5

1/2 x X - 1/3 = 5/3 - 7/5

1/2 x X - 1/3 = 4/15

1/2 x X = 4/15 + 1/3

1/2 x X = 9/15

X = 9/15 : 1/2

X = 18/15.
