How to solve direct variation
There are a few steps to solving a direct variation problem. First, identify the two variables involved and the constant of proportionality. Then, create an equation using the known values and the constant of proportionality.
How can we solve direct variation
Finally, solve the equation for the desired variable.
A direct variation is a proportionality between two variables, in which one variable is a multiple of the other. For example, if y varies directly as x, and we know that y = 10 when x = 5, then we can find the value of y when x = 2 by multiplying 5 by 2, which equals 10. In general, if y varies directly as x, and y = k when x = a, then we can find the value of y when x = b by
To solve a direct variation problem, you need to find the constant of variation, which is the proportionality constant between the two variables. This can be done by either graphing the data or by using the equation y = kx. Once you have the constant of variation, you can use it to solve for any other variable in the problem.
Direct variation occurs when two variables are directly proportional to each other. In other words, one variable increases while the other variable decreases (or vice versa). To solve direct variation, you need to find the constant of proportionality, which is the ratio of the two variables.
There are a few steps you can take to solve direct variation equations. First, identify the constant of variation. This is the coefficient that is always multiplied by the variable. Next, plug in known values for the variable and solve for the constant. Once you have the constant, you can plug in any other known value for the variable and solve for the corresponding value of the other variable.

Absolutely Superb app. Wish I could give it 10 Stars. I couldn't have made it through math without this. All you have to do is take a picture and it not only solves it, using any method you want, but it also shows and EXPLAINS every single step.
very helpful. there are a few expressions they can't yet solve like word sums and the language you can choose to read word sums. but it is very helpful and a life saver. legendary app.
