Sure you can substitute that. You just have to be careful to avoid division by zero - but the same may happen with other numbers as well. For example:
- If you have a denominator "x", then you can't substitute "x" by zero.
- If you have a denominator "x - 1", then you can't substitute "x" by 1, because if you do, the denominator will be zero.

What is 555 - 555 - 55 x 0?
The expression can be simplified step by step. First, calculate the multiplication: (55 \times 0 = 0). Then, substitute that back into the expression: (555 - 555 - 0). This simplifies to (555 - 555 = 0). Therefore, the final result is (0).
How do you write -8 increased by the quotient of 13 and a number as variable expression?
-8 + 13/N, where N ≠0.
What is 20 plus 40x divided by 20x and are there any restrictions on the variable?
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
What is a mathematical phrase with at least one variable?
A mathematical phrase with at least one variable is an expression that includes numbers, operations, and one or more letters representing unknown values. For example, the expression ( 3x + 5 ) contains the variable ( x ) and represents a relationship where ( x ) can take on different values. Another example is ( 2y - 7 = 0 ), which includes the variable ( y ) and represents an equation.

Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
What is a quadratic expression?
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
What is 555 - 555 - 55 x 0?
The expression can be simplified step by step. First, calculate the multiplication: (55 \times 0 = 0). Then, substitute that back into the expression: (555 - 555 - 0). This simplifies to (555 - 555 = 0). Therefore, the final result is (0).
In the exponential expression a raise to negative n is a positive integer the variable a cannot be equal to zero Explain why this is so?
a^(-n) = (1/a)^nIf a is 0, the above expression would require division by 0, which is not defined.
How do you write -8 increased by the quotient of 13 and a number as variable expression?
-8 + 13/N, where N ≠0.
What is 20 plus 40x divided by 20x and are there any restrictions on the variable?
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
Is a expression the number multiplied to a variable?
An expression can be that, but it can also be a combination of such terms and other mathematical operations. For example, 3a + 27b^2/sin(27c) provided c is not 0.

What is the difference between a numerical expression and a algebraic expression?
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
What is the value of (x 6)(x-1)when x1?
To find the value of ((x + 6)(x - 1)) when (x = 1), substitute 1 into the expression: [ (1 + 6)(1 - 1) = (7)(0) = 0. ] Thus, the value is 0.
