Question

Explain what is a linear equation what is it used for?

Answer 1

For example, if you are the office is 20 miles from your office, and you have reach 8 am, and you know that the traffic is moving at 40 miles per hour.

To know what time you should leave from home, use this equation

Time taken = distance/ rate of travel

t= 20/40 = ½ or half an hour. To reach the office at 8 a.m., you should leave home at 7: 30 am

Answer 2

To calculate or solve problems involving distance, speed and time we used linear equation, it is also used to find solutions that involve weight, mass and density. Linear equation can be expressed as Ax +By+ Cz+…= D.
