The difference of twice a number and five is three. Find the number

The number is 4.

The step describe to solve the problem is: add five and then multiply by

Step-by-step explanation:

Let the number be x.

As per the given condition as:

The difference of twice a number and five is three.

"Twice a number" means

"difference of twice a number and five" means

therefore, the translation of the given word problem to an equation is:

Now, solve the equation :

Addition Property of equality states that you add the same number to both sides of an equation.

Add 5 to both sides of an equation we get;

2x-5+5=3+5

Simplify:

2x = 8

Multiplication property of equality states that you multiply the same number to both sides of an equation.

Multiply by  both sides we get;

Simplify:

x = 4

The steps which describe to solve the problem is: add five and then multiply by

Therefore, the number x = 4

4 the answer is four as 4×2=8 and 8-5=3

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
