Question

4х-19​

Answer 1

Ответ:

$4x - 19 \times \frac{3}{5} = 23 \\ 4x = \frac{57}{5} + 23 \\ 4x = 11 \frac{2}{5} + 23 \\ 4x = 34.4 \: \: \: \: \: | \div 4 \\ x = 8.6$

Answer 2

The expression "4x - 19" is an algebraic expression that represents a mathematical relationship. It consists of two terms: "4x" and "-19."

• The term "4x" represents the product of 4 and the variable "x." In algebra, this is a common way to denote multiplication. It means you're multiplying 4 by the value of "x," whatever "x" represents.

• The term "-19" is a constant, meaning it's a fixed value and doesn't depend on any variable.

If you have a specific value for "x," you can substitute it into the expression to find the result. For example, if "x" is equal to 5, then:

4x - 19 = 4(5) - 19 = 20 - 19 = 1

So, when "x" is 5, the value of the expression 4x - 19 is 1. The result will vary depending on the value you assign to "x."
