The answer is x = 5. By rearranging the equation, we can isolate the variable x. Subtracting 3x from both sides gives us 5 = x.
It is an equation in a single variable, x.
It is an equation in the variable r.
5x+4y=20 is technically the equation of a line. A more familiar representation of the line is in "y equals" notation. This simply means that the y variable has been isolated (this notation is usually required for graphing calculators). To get the equation in y equals notation, simply isolate the y variable: 5x+4y=20 4y=(-5)x+20 y=((-5)x+20)/4
It is a linear equation in one variable, x.
To solve the equation 3n = 3x5, you first need to isolate the variable n. Divide both sides of the equation by 3 to get n = 5. Therefore, the answer is n = 5.
it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
The answer is x = 5. By rearranging the equation, we can isolate the variable x. Subtracting 3x from both sides gives us 5 = x.

State the problem: 35q = 5 Solve for q by dividing both sides by 35 (to isolate the q variable): q = 5 ÷ 35 or 5/35, simplified to 1/7, or 0.142857 in decimal form.
