Answer:

[tex]\fbox {Required equation : 4(x + 3) = 20}[/tex]

[tex]\fbox {Result : x = 2}[/tex]

Step-by-step explanation:

Let our number be x.

1) 3 is added to this number.

  • x + 3

2) It is multiplied by 4.

  • 4(x + 3)

3) It is equated to 20.

  • 4(x + 3) = 20

∴ This is our framed equation.

Steps to solve :

1) Divide by 4 on both sides.

  • 1/4 x 4(x + 3) = 20/4
  • x + 3 = 5

2) Subtract 3 on both sides.

  • x + 3 - 3 = 5 - 2
  • x = 2

∴ The number is 2.
