13+13+13+13+13+13+13+13+13+13 = 13 * 10 = 130.
3x+5 = 2x+13 3x-2x = 13-5 x = 8
(6x + 1)(x + 13)
5x - 4x = 13 - 3 ie x = 10
-20 + 13 = -7
If that's the equation 6r + 7 = 13 + 7r, r = -6
91
13 plus 13 is equal to 26
Plus 12 plus -13 plus plus 1 can be rewritten in mathematical terms as: 12+(-13)+1 or 12-13+1 12-13+1 =-1+1 =0
It is: 5+13+18 = 36
17x + 13
(13+5)18=13+(5+18)
13 x 3 JHC!
If: x+0 = 13 then x = 13
= 18x + 13
17 plus 15 plus 13 equals 45.
yes it is
13 plus 13 would equal 26.
