Question

PLEASE HELP 10 POINTS

Answer 1

Well 7 * 2 is 14 and 7 * 1 is 7 so 14 + 7 is 21. That means the other side of the equation has to equal 21.

2 + 1 is 3 and 21/3 is 7 so the number 7 goes in the blank

Hope this helps!!

Answer 2

Your answer would be 7

(7 x2)=14

(7 x 1)= 7

14 + 7=21

(2+1)=3

21=3(x)

21/3=7

x=7

Hope this helps :)
