It means to find what numbers the variables (the letters) must be
in order to make the equation a true statement.
an equation is a number sentence with and = sign
What do you mean by "solve"? This is not an equation.
Break it down till you cant anymore!
its mean solve the problem, to fine the solution like what makes it work.
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
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.
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)
