What else can I help you with?
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 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.
What number when substituded for the variable in an equation makes the equation true?
you have to solve the actual equation in order to answer this about your variable
Can you solve for a variable in an expression or equation?
you can only solve for one in an equation so it can equal something
Can you solve a variable with an equation?
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.

What does SOLVE stand for in math?
"Solve an equation" means "find out, for which values of the variable or variables is the equation true".
How do solve for the variable over a number in a linear equation?
Well a variable in a number in a linear equation is basically the variable divided by a number. So if you have x over 10, it is basically x times 1/10. You can solve by having either another equation and use either point slope or y=mx+b.
How do you solve a 2 step equation with a fraction and variable?
To solve a two-step equation with a fraction and a variable, first isolate the term with the variable by eliminating any constant on the same side. You can do this by adding or subtracting the constant from both sides. Next, if the variable is multiplied by a fraction, multiply both sides of the equation by the reciprocal of that fraction to solve for the variable. Finally, simplify to find the value of the variable.
