Answer:

18

Step-by-step explanation:

Let the required number be x.

<h3>Step 1</h3>

write the expression for the difference of the number and 4.

=> x - 4

<h3>Step 2</h3>

the question equates 5 times the difference with some other terms, so find the equation for 5 times the difference.

=> 5( x - 4)

<h3>Step 3</h3>

The equation in Step 2 is said to be equal to "two less than four times the number".

Find the expression for four times the number

=> 4x

<h3>Step 4</h3>

Find the expression for two less than 4x.

=> 4x - 2

<h3>Step 5</h3>

Equate the terms that it says are equal:

=> 5(x - 4) = 4x - 2

<em>distributing</em><em> </em><em>5</em><em> </em><em>within</em><em> </em><em>the</em><em> </em><em>parenthesis</em><em>:</em>

=> 5x - 20 = 4x - 2

<em>t</em><em>a</em><em>k</em><em>i</em><em>n</em><em>g</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>on</em><em> </em><em>one</em><em> </em><em>side</em><em>:</em>

=> 5x - 4x = 20 - 2

  • (the sign carried by the terms get inverted while changing their sides)

=> x = 18

<em>and x was the required number, so the answer Is 18. </em>
