What is the issue with Juul pods/ E-cigarettes and the environment?

The issue with Juul pods/E-cigarettes is that lots of people(teenagers) are smoking it and it isn't good for them. There are microscopical metals in the E-cigarettes that damage your lungs when smoked. Even though they aren't as bad as real cigarettes they still have nicotine in them and instead of lung cancer smoking the Juuls/E-cigarettes gives you wet lungs.

Explanation:

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
