No. If you let 'x' =0 then 'x' is zero and there's no reason to solve for it.
At the x-intercept ... just like at any point on the x-axis ... 'y' is zero.
Let 'y' equal zero, then solve for 'x'.
x2 = -25 There exists no real number for which this is true, so we must use imaginary numbers... x = 5i
-4
If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.
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.
True. Three cubed equals twenty-seven
You cannot solve it since it is not a true equation.
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
You cannot because it is not a true statement.
First, you have to know what 'solve' means, so you know what you're looking for.'Solve' means find a number for 'x' that will make the problem a true statementwhen you plug that number in wherever 'x' appears.Here's how to find it. First, write the problem down and look at it:x - 5 = 2xNow subtract 'x' from each side:-5 = xAnd there you are.
true
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
An equation is a true statement. [ 75 + 4 = -2 ] is a false statement.
It cannot because neither statement is true.
x2 = -25 There exists no real number for which this is true, so we must use imaginary numbers... x = 5i
The equation has no solution. Since if you combine like terms, you get 0=-10 which isn't true, there are no solutions to the equation.
To solve something is to find a value or situation such that a given statement or situation is true. A puzzle, a crossword, an equation, a crime etc may be solved.
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
