That depends what the value of b is.
7 Brides for 7 Brothers
The ditloid 7 equals B for S B (7 = B for S B) means:7 = Brides for Seven Brothers
7 Brides for 7 Brothers.
a = b/7
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
7
-1
b times 7
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
b^2 + 8b + 7 factors to (b + 7)(b + 1)
The number is 34 a + b = 7 a = 7 − b 10a + b + 9 = 10b + a 10(7 − b) + b + 9 = 10b + 7 − b 70 − 10b + b + 9 = 9b + 7 72 = 18b 4 = b 3 = a
