Question

15 - 2 X upon 5 - 4 x + 3 upon 2 is equal to zero​

Answer 1

Answer:

15/4

Step-by-step explanation:

15- 2x/5 - 4x + 3/2 = 0

(150 - 4x - 40x + 15)/10 = 0

165 - 44x/10 = 0

165-44x = 0

44x = 165

x = 165/44 = 15/4

substituting x as 4,

15-2(15/4)/5 - 4(15/4) + 3/2 =0

15- (15/2)/5 - 15 + 3/2 = 0

-15/10 + 3/2 = 0

(-15 + 15)/10 = 0

0/10 = 0

0 = 0
