Question

A positive number is 3times another number, If 3 is added to the smaller number,the difference between new number and greater becomes 31.what are the numbers?

Answer 1

• ANSWER:)
• ANSWER:) let the no be x and 3x
• ANSWER:) let the no be x and 3x3x-(x+3)=31
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=31
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=312x=31-3
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=312x=31-32x=34
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=312x=31-32x=34X=34÷2
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=312x=31-32x=34X=34÷2X=17
• ANSWER:) let the no be x and 3x3x-(x+3)=313x-x-3=312x=31-32x=34X=34÷2X=17EXPLAINATION:)

Answer 2

Answer:

bigger no=51

smaller no=17

Step-by-step explanation:

the bigger no equal to 3x

the smaller no equal to x

so if 3 is added to smaller no then it become=x+3

so the equation form=

3x-(x+3)=31

3x-x-3=31 [ the minus out of bracket is multipled by the no inside the bracket]

2x-3=31

2x=34

x=17

so smaller no equal to x=17

and bigger no equal to 3x=17×3=51
