Gian is allowed to spend 45 minutes on the computer after dinner. he spends his entire 45 minutes either watching videos or playing games. write an equation for the number of minutes gian spends playing games, y, if he spends x minutes watching videos.

45-y=x

Step-by-step explanation:

total=45 minutes

45-y=x because you have to subtract y the amount of minutes Gian spent playing games to find how many minutes he has left to watch videos in his 45 total minutes. Hope this helps!

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
