If that's the equation 6r + 7 = 13 + 7r, r = -6
X=6
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
25x+1=33x+7 25x=33x+6 -8x=6 x=-8/6 x=-4/3
7 + 6 = 13
13
-y + 7 = 13 -y = 6 y = -6
n=6
-6
p + 7 = 13 p = 6
7+6
-6
8+5 = 6+7 = 8+9 13 = 13 = 17 Can you rephrase? the question isn't too clear...
the answer is 6
273 13+8 = 21 and 13*21 = 273
6+8=14
