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.
2) It is multiplied by 4.
3) It is equated to 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.
∴ The number is 2.
