I assume that you mean that you are given a differential equation dy/dx and want to solve it. If that is the case, then you would multiply by dx on both sides and then integrate both the left and right sides of the equation.
Something needs to be an EQUATION in order for you to be able to SOLVE it. There's no "=" here so it's not an equation. What is the space between 3y and 21 supposed to mean? Clean it up!
it is not an equation (there no equality in it!)
Solve the equation for x, and enter your answer in the box below.
variable equation solve it test it
an equation is a number sentence with and = sign
What do you mean by "solve"? This is not an equation.
its mean solve the problem, to fine the solution like what makes it work.
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
you don't answer an equation, you solve an equation
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
solve it
If you solve such an equation for "y", you get an equation in the slope-intercept form.
It means to solve what is known (answer the equation)
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
