When you sign up for video games are you get 400 points you earn 50 more points for each hour that you play how many hours do you have to play to get 1000 points

This is a linear equation
y=mx+b
y=50x+400 (when x equals the number of hours played)

1000=50x+400
*first, isolate the variable (x)
-50x=-1000+400
*divide by -50 to get x by itself
x=20+8

The answer is x=28
