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.
True. Three cubed equals twenty-seven
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.
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.
