Then use the literal equations solution to obtain the solution 3x=-15

well this is smthing related to math but here's how we do it :

3x = -15   3x is in multiplication form and when it comes to the right it changes to division formwhich will become

x = -15/3  and if we divide 3 and 15 we get 5 as 3 × 5 = 15

and as (+) and (-) = (-) ... the answer will be negative ... so the answer is -5

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
