Respuesta :

more means add so you add 3+
then you multiply 2
so now you have 3 + 2 x 7= 25
you can check it by doing 3 + 2= 5 x 7=25

Answer:

the number is 4

Step-by-step explanation:

Hello,I think I can help you with this

Step 1

convert into mathematical terms

let x the unknown number

three more: 3 +

twice the sum of 7 and a number:2(7+x)

is 25:=25

Hence

3+2(7+x)=25

Step 2

Now, solve for x

3+14+2x=25

17+2x=25

2x=25-17

2x=8

x=8/2

x=4

the number is 4

Do not hesitate to ask me if you have any concerns

Have a great day.
