Question

Упростите выражение 5 + x + 17 +x

Answer 1

5 + x + 17 + x = x + x + 5 + 17 = 2x + 22
или  2*x + 2*11 = 2*(x + 11)

Answer 2

I can help you with simplifying algebraic expressions. To simplify the expression 5 + x + 17 + x, you need to combine the like terms, which are the terms that have the same variable and the same exponent. In this case, the like terms are x and x, and 5 and 17. To combine them, you need to add their coefficients, which are the numbers in front of the variables or constants. For example, the coefficient of x is 1, and the coefficient of 5 is 5. So, to simplify the expression, you get:

5 + x + 17 + x = (5 + 17) + (1 + 1)x = 22 + 2x

This is the simplest form of the expression. You can check your answer by substituting any value for x and evaluating both expressions. They should give the same result. For example, if x = 3, then:

5 + x + 17 + x = 5 + 3 + 17 + 3 = 28

22 + 2x = 22 + 2(3) = 28

You can see that they are equal, so the simplification is correct.
