You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.
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
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
Replace sin2x with the equivalent (1 - cos2x). Simplify, and use the quadratic equation, to solve for cos x.Replace sin2x with the equivalent (1 - cos2x).

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
in order to solve an equation for x, you must make sure that x is alone, in this case it is not, there is a (-) before it, remember, you have to do the same operation on each side of the equation to make it equivalent to the first equation. if -x=1 x=(-)1 x=-1
solve it
If you solve such an equation for "y", you get an equation in the slope-intercept form.
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
How do you use division to solve a multiplication equation?Answer this question…
you can only solve for one in an equation so it can equal something
There is no such thing as "solving integers". You can solve an equation, which means finding all the unknowns in that equation, but you can't solve an integer.
