Answer:

So you can cancel out the 16. See, the -16 is negative, and if we add +16 to it, then it cancels out and is 0. That way, you have x=1.

Step-by-step explanation:

-16x+x=-15

+16x      +16

   0+x=1

       x=1

Answer:

Step-by-step explanation:

hello

2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4  \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by  \ \ 2\\

so the solution is 2

5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4  \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by  \ \ 5

so the solution is 4/5

hope this helps

Can someone help with this please!!
Ksenya-84 [330]

Answer:

D) L+S=9 ; 6L+3S=9

Step-by-step explanation:

Given this information, we know that the total number of large and small Ubers must be 9, so we can eliminate choices A and C as the first part of the system of equations is L+S=9

Also, since the large Ubers can fit only 6 people per vehicle and the small Ubers can only fit 3 people per vehicle, then we can eliminate choice B as the second part of the system of equations is 6L+3S=39

Therefore, the only correct choice is D
