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.
How do you evaluate an algebraic expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
What is the answer to algebraic expression b plus 1?
The answer is b+1. Therefore the algebraic expression for this is b+1
Evaluate the expression for the given value of the variable 5y - 1 for y equals 3?
14
2m plus 1-7m plus 5m?
When simplified it is just: 1
How do you solve x plus 1 over x?

Describe how to evaluate a variable expression?
1/2w+2
What is b plus 1 as an algebraic expression?
b + 1 is b plus 1 as an algebraic expression.
Evaluate 3 open parentheses10x plus y close parentheses plus 2x plus 7y?
3(10x + y) + 2x + 7y (multiply the 3 through the parentheses then combine like terms) = 30x + 3y + 2x + 7y = 32x + 10 y Evaluate an expression for some values of x and y, means to substitute those values into the expression, such that when x = 3 and y = 1 the value of the given expression is 106: 32x + 10y = 32(3) + 10(1) = 96 + 10 = 106
What sequence does the arithmetic variable 5n plus 2 represent?
Put n = 1, 2, 3, 4 etc in the expression 5n + 2 and evaluate to get the sequence.
How do you evaluate 12 plus -1 plus -1 plus 3?
It evaluates to: 12+(-1)+(-1)+3 = 13
What is the answer to the expression 1 plus 1?
2!
How xy plus x plus y plus 1 will solve?
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
How do you evaluate an expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
How do you prove by induction 1 plus 3 plus 32 plus 33 plus ... plus 3n plus 1?
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
What is value of an expression?
When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
How do you evaluate an algebraic expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
