When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
As many solutions as there are points in the domain.
n - 8 = 5 n = 13
X = 29 - 14 (therefore X=15)
You would use several properties. The first is that performing the same operation to both sides of an equation is valid. Next the multiplicative inverse property of 1/7 (with respect to 7).
-g is really -1g so divide -1g by -1. what you do to 1 side, you have to do to the other side. so divide 35 by -1. the solution is g= -35
k is the variable.
To completely isolate the variable, we have to divide both sides of the equation by 6. x = 24 / 6 x = 4 Now, x is all by itself or "isolated". We can read the answer right from the equation. x equals 4. To review, isolating the variable means getting every term containing the variable on one side of the equationfound on google...
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.
"Wat" is the variable.
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
