In a class of 50 student,18 offered mathematics, 21 offered chemistry while 16 offered biology, 7 student offered mathematics and biology, 9 student offered chemistry and biology while 5 student offered the three subjects. find the number that offered mathematics but neither chemistry nor biology. b the number of students that offered biology but neither chemistry nor mathematics and the number that offer biology neither mathematics nor chemistry​

not wrth aswering

Step-by-step explanation:

ill try:

18 - 7 = 11

11 - 5 = 6

6 offered math but neither chem nor bio.

16 - 7 = 9

9 - 9 = 0

0 - 5 = -5

so 0 offered bio but neither chem nor math.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
