Express equations are mathematical equations that explicitly outline a variable when it comes to different variables. Division is a mathematical operation that entails dividing one quantity by one other.
In some instances, it could be mandatory to write down an specific equation with division.
This could be carried out in a scenario the place we all know the worth of 1 variable,
and need to discover the worth of one other variable.
For instance, if we all know the full price of a purchase order, and the price of every merchandise,
we are able to use division to search out the variety of gadgets bought.
To put in writing an specific equation with division, we merely have to isolate the variable that we need to outline on one aspect of the equation, after which divide each side by the coefficient of that variable.
For instance, if we now have an equation akin to:
2x + 5 = 13,
we are able to isolate `x` on one aspect of the equation by subtracting 5 from each side:
2x = 8
after which divide each side by 2:
x = 4
Subsequently, the express equation with division for this equation is:
x = 13 / 2
Easy methods to Write an Express Equation with Division
To put in writing an specific equation with division, comply with these steps:
- Determine the variable being divided.
- Divide each side of the equation by the variable.
- Simplify the equation.
For instance, to write down the express equation for the perform f(x) = 3x + 2 / x – 1, we might first determine x – 1 because the variable being divided. Then, we might divide each side of the equation by x – 1:
(3x + 2 / x – 1) / (x – 1) = (3x + 2) / (x – 1)
Lastly, we might simplify the equation:
f(x) = 3 + 2 / (x – 1)

What’s an specific equation?
An specific equation is an equation that expresses one variable when it comes to the opposite variables.
How do I examine if my specific equation is right?
To examine in case your specific equation is right, substitute the worth of 1 variable into the equation and see if the result’s the opposite variable.
