Add 3 to my number and then multiply the result by 5 the answer is 35

7x5=35? I'm sorry if this is incorrect. I tired i'm not exactly sure.

Number=x since unknon

add 3 to x

3+x, thenmultiply by 5

(3+x) timmes 5 answer is 35

5 (3+x) = 35

now distribute useing distributive property

a (b+c) = ab+ac

5 (3+x) = 15+5x

15+5x=35

subtract 15 from both sides

5x=20

divide both sides by 5

x=4

the nuber is 4
