13 = 7 + s(13 - 7) = (7-7) + s6 = s
no it;s not the answer is 2
Doc, Happy, Grumpy, Sleepy, Bashful, Sneezy and Dopey equal[s] the 7 dwarves.
7z + 6s + s = 7z + 7s This can then be factorised using 7 as the factor: 7z + 7s = 7(z + s)
the x's are -7's
s = 7, t = -3
9s + 7 = -11 9s = -18 s = -18/9 s = -2
-1
7+7+7+7+7+7+7/7=43 7 times 6=42 plus 1 whole=43
s would be the variable in this equation and after calculating it would be 6/7
s = -70
