$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
X&({{ 2}}\quad ,&{{ 4}})\quad

Z&({{ x}}\quad ,&{{ y}})

% coordinates of midpoint

\left( \cfrac{x+2}{2}~,~\cfrac{y+4}{2} \right)=\stackrel{Y}{(-1,1)}\implies 
\begin{cases}

Write the following using algebraic notation, using the letter x for any unknown numbers:

Furkat [3]

Answer:

a) The algebraic notation is 4 ( x -3 ) = 4x -3

b) The algebraic notation is 2x +2

Step-by-step explanation:

<u><em>Explanation:-</em></u>

a)

Let 'x' be the number

Given 'x' is a number, subtract three

⇒ x - 3 and multiply '4'

The result of algebraic is 4 ( x -3 ) = 4x -3

b)

<em>Let 'x' be a number and add one</em>

⇒ (x+1) and then double

∴ The algebraic notation is

(x+1 ) (2) = 2x +2
