X=7/3
solution steps:
subtract 2 from both sides
subtract 2x from both sides
Answer:
6 hours
Step-by-step explanation:
Suppose Madison spent x hours on her social project,
then the number of hours spent on other project will be 1/3 of x=x/3
Total hours spend on all projects will be the addition of hours spent on social project and hour spent on other project, i.e
x + x/3 = 4x/3
It si given that this is 8 hours, therefore
4x/3=8
Multiplying both sides by 3:
4x=24
Dividing across board by 4:
x= 6 hours
Answer: number= 5.5; equation: 4x+8=30
Step-by-step explanation:
Take x for the unknown number. Then just follow the words and turn them into mathematical symbols. Easy.
It is y=x-150 because x−150+150=y+150
