Question

Write a word problem which can be solved using the expression 2x+50

Answer 1

Answer:

friend this is not a formula

Step-by-step explanation:

ax ± b = c. All problems like the following lead eventually to an equation in that simple form.

Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?

Solution. Every word problem has an unknown number. In this problem, it is the price of the blouse. Always let x represent the unknown number. That is, let x answer the question.

Let x, then, be how much she spent for the blouse. The problem states that "This" -- that is, $42 -- was $14 less than two times x.

Here is the equation:

2x − 14 = 42.

2x = 42 + 14

= 56.

x = 56

2

= 28.

The blouse cost $28.
