What is3 x-4 is an expression or equation?
7
What is the solution set for the equation 2x plus 4?
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
What is the equation 2 to the power of 4?
2 to the power of 4 is an expression, it is not an equation.
Do all algebraic expressions have to have variables for example would 3 plus 4 equals 9 be an expression or would it need to be n plus 4 equals 9 to be an expression?
3 + 4 = 9 is not an expression, it is an equation (which happens to be false). An equation without a variable is simply a statement which is either true (a tautology) or false. It's main use is probably at the end of a proof where you may show that the left hand side of some equation is numerically the same as the right hand side which proves your proposition. n + 4 = 9 is also not an expression, but an equation. An equation with a variable can divide the domain into distinct partitions such that the equation is true if the value of the variable is within those partitions and not if they are outside. This may enable you to derive further information about he variable(s).
What is the value of the expression 3x plus 4-2y if x equals 5 and y equals -3?
3x+4-2y x=5 and y=-3 You substitute these values into the original equation. 15+4+6 = 25
Is 3a-14 equals 4 an expression or an equation?
An equation.
What is3 x-4 is an expression or equation?
7
What is four less than an age in algebraic expression?
say X equals the age, the equation would be:x - 4 = ?
What is the solution set for the equation 2x plus 4?
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
What is the equation 2 to the power of 4?
2 to the power of 4 is an expression, it is not an equation.
How do you solve six plus the product of four more than a number and three?
6 + (4 + n)*3 is an expression, not an equation. An expression cannot be solved since there is no equals sign in it.

If the expression 15y-4 has a value of 41 what is the value y?
To find the value of y in the expression 15y-4 = 41, you need to isolate y. Start by adding 4 to both sides of the equation to get 15y = 45. Then, divide both sides by 15 to solve for y, which equals 3. Therefore, the value of y in the expression 15y-4 when it equals 41 is 3.
What is the value of the expression 3x plus 4-2y if x equals 5 and y equals -3?
3x+4-2y x=5 and y=-3 You substitute these values into the original equation. 15+4+6 = 25
How do you write an algebraic expression for the sum of a number and -6 is 4?
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
What is a math expression?
An expression is the sum (or difference) of two or more terms. Example 3x + 2y is an expression.It is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have an expression if there is not an = signYes the 6 + 1 part is an expression. If you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence.
What is the differences between an algebraic expression and an algebraic equation?
an algebraic expression has no = sign. it could be like x+4, but an equation has to have an = sign. like x+4=5
