Answer:
(number one) b = 11/30
(number two) v= -23/15
Step-by-step explanation:
(number one) 1- 10 (1+3b)= -20 (distribute)
-1-10-30b = -20 ( add the like terms)
-9 - 30b = -20 (move -9 to the right)
-30b = -20 + 9 (calculate)
-30b = -11 (divide)
b = 11/30
(number two) 2-6(1-5v) = 54 (change the negative to a positive)
2+6 (1-5v) = 54 (distribute)
2+6-30v= 54 (add the like terms)
8- 30v = 54 (move 8 to the right)
-30v = 54-8 (subtract the number)
-30v = 46 (divide)
v = -46/30 (reduce the fraction)
v= -23/15
