11 + 7 + 9 = 27

-7 + 11 = +4

11

4 + 7 = 11

x-7+7=11+7 x=11+7 x=18

7

= 3

7 + 4 = 11

7*7+11*10=159

The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.

x = 11/7 and y = 12/7

-11

If: 7+t = 11 Then: t = 11-7 So: t = 4

It doesn't, 7+2=9

You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7

4 plus 7 equals 11. 4 multiplied by 7 equals 28. 4 divided by 7 equals .57. 4 minus 7 equals -3.

9y subtract 11 equals 7

x/11 + 21 = 7 x/11 = -14 x = -154

x/11 + 21 = 7 x/11 = -14 x = -154
