You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5

and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as:

xy = 10

you divide both sides by "x".

You cannot solve a single linear equation with two variables. At best you can express one variable in terms of the other.


How do you solve 5t-5 equals 5t plus 7?

You don't for t, as gathering your coefficient variables together = 0 5t - 5 = 5t + 7 now, subtracting 5t from either side to get the variables on one side of the equation renders this. - 5 does not = 7

What is an equation with one or two variables?

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

A feasible solution, which when applied means that all the variables etc... on one side of the equation equal to whatever is on the other side of the equation.


How do you write an equation that works in forward and reverse?

You can write an equation that works in forward and reverse by setting the same variables on either side. Alternatively you can set offsetting variables on each side which will also create the same results.


What are the 4 methods to solve a quadratic equation?

You can solve a quadratic equation 4 different ways. graphing, which is quick but not reliable, factoring, completing the square and using the quadratic formula. There is a new fifth method, called Diagonal Sum Method, that can quickly and directly give the 2 roots in the form of 2 fractions, without having to factor the equation. It is fast, convenient, and is applicable whenever the equation can be factored. Finally, you can proceed solving in 2 steps any given quadratic equation in standard form. If a=1, solving the equation is much simpler. First, you always solve the equation in standard form by using the Diagonal Sum Method. If it fails to find answer, then you can positively conclude that the equation is not factorable, and consequently, the quadratic formula must be used. In the second step, solve the equation by using the quadratic formula.


How do you solve for x when multiplying fractions?

You solve just like any other equation: You try to manipulate your equation so that the "x" is alone on the left side, and everything else on the right side.


Which is the best way to solve the equation?

That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.


How do you solve an equation using addition and multiplication principles?

The exact procedure to use can only be decided after you examine the equation. Different equations are attacked in different ways. All I can tell you in general is: Whatever you do to one side of the equation, you must immediately do the same to the other side. Follow this rule enough times, and you'll eventually be looking at the equation's solution.
