Practice -Make linear equation from everyday situation
Questions :
You are 5 years older than your brother. Make a linear equation to find out your age.
You earn 5 times more than your friend. Make a linear equation to express your earning.
You went to a store with $75 in your pocket. You spent $5 every hour in the store :(. Make a linear equation to express the amount of money you will have in your pocket with time.
You have started working in a store. You earn $15 per hour. If you owe $12 to your friend, write a linear equation to express the amount of money you will earn after working for a few hours.
Explanations :
Your age = Your brother’s age + 4
Assume,
Your age = y
Your brother’s age = x
So the linear equation is :
y = x + 4
Video Explanation :
Your earning = Your friend’s earning x 5

Your earning = y
Your friend’s earning = x
So the linear equation is :
y = 5x
Video Explanation :
y = – 5x + 75
Video Explanation :
y = 15x – 12
