What is an Equation?
An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
Joey wants to buy a used car,
The cost of the car is $2500.
The money he has saved is $1200
The money he makes by walking a dog is $50 per week.
Let w represent the number of weeks.
The equation for the condition can be written as:
The cost of the car is equated with the money he has and the money he earned in w weeks by dog walking.
2500 = 1200 + 50w
To determine the number of weeks he has to work to buy the car, the equation has to be solved for w,
50w = 2500 - 1200
50w = 1300
w = 1300 / 50
w = 26 weeks.
