Answer 1

`\fbox {Required equation : 4(x + 3) = 20}`

`\fbox {Result : x = 2}`

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.
