Can someone write atleast 5 sentences on why cars are helpful. (Ill give brainliest)

Cars are helpful because they are just like property, and I doubt you want your house to be gone randomly. Another reason they are helpful is because it helps with transportation. You can go to the mall, stores, and more. If we didn't have cars, we would use all of our energy trying to get to places. Cars are also cool.

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
