That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.
There is no "best" way: there are different ways for different equations.
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
No.
it is not an equation (there no equality in it!)
you have to focus on your unit and try your best by the way its your teacher
Solve the equation for x, and enter your answer in the box below.
It depends on which variable you wish to solve for.
Take the square root of both sides of the equation
Without an equality sign the given expression can't be considered to be an equation.
do you mean, x2 = n?? Take the square root.
You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
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
solve it
If you solve such an equation for "y", you get an equation in the slope-intercept form.
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
