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 is a variable expression that has a decreasing value as the value of the variable increases?
what is a variable expression that has a decreasing value as the value of thevariable increases?
What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
How do you solve x plus 1 over x?
You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
What does the variable represent in an addition or subtraction expression?
it is the number you would use to solve the problem
What is to find the value of a numerical or algebraic expression?
to solve for the variable
To solve a system of equations you cannot replace a variable with an equal value or expression?
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
How do you solve one let statements in math?
Assigns the value of an expression to a variable or property.
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.
Can you solve a system of equations you can replace a variable with an equal value or expression true or false?
True
What is a variable expression that has a decreasing value as the value of the variable increases?
what is a variable expression that has a decreasing value as the value of thevariable increases?
What is it called to carry out math operations in the correct order or substitute a value for a variable and solve an expression?
Order of Operations
How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!

What does it mean to evalutate the expression?
Replace each variable in the expression by its value and then find the value of the expression.
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
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
