How do you solve an equation with 1 variable?

Why can't you use a equals equals sign for a for statement?

This answer applies to programming languages in general. The equals sign is used for assignment. For example, the code "$variable = 1" assigns the value of 1 to the variable $variable. If you want to test whether values are the same (equality) the double equals sign is used. For example, when you want to verify that $variable has been assigned the value of 1 you would use: $variable == 1


What does count equals count plus 1 and total equals total plus 1 in algorithm means?

This is an instruction to increment the value of a variable by 1 (in this case, either the variable count or the variable total).

If you were to solve the following system by substitution what would be the best variable to solve for and from what equation?

To determine the best variable to solve for in a system of equations by substitution, look for the equation that allows you to isolate a variable easily. Typically, choose the equation where one variable has a coefficient of 1 or -1, or is already expressed in terms of the other variable. This makes substitution straightforward and minimizes complexity in calculations. Once identified, you can solve for that variable and substitute it into the other equation.


How do you solve the problem 15 plus 4m equals -1?

15+4m=-14m=-16 (subtract 15 from both sides to isolate variable (4m))m=-4 (divide each side to isolate variable from coefficient)

How can you use substitution method to solve a system of equation that does not have variable with a coefficient of 1 or -1?

To solve a system of equations using the substitution method when no variable has a coefficient of 1 or -1, first isolate one variable in one of the equations. You may need to manipulate the equation by dividing or rearranging terms to express one variable in terms of the other. Once you have this expression, substitute it back into the other equation to solve for the remaining variable. Finally, substitute back to find the first variable.


Is the random variable x equals 1 be stated that the random variable is discrete?

If x = 1 then X is not really a random variable but a constant.


What is the square root of x to the ninth?

the square root (abbreviated: sqrt) of x9 can be written like this: sqrt(x9) = (x9)(1/2) = x[9*(1/2)] = x(9/2)


Solve by substitution y equals -4x - 7 and y equals 3x?

The easiest way to solve this system of equations is to solve for a variable in one of the equations. In the second equation, y = 3x. This can be substituted into the first equation: y = -4x - 7; 3x = = -4x - 7; 7x = -7; x = -1. Since we have determined that x equals -1, we can then substitute -1 into either equation to find our corresponding y-value. Thus: y = 3x; y = 3(-1) y = -3. Thus, the solution to this system of equations is (-1, -3).
