the number of gallons of water in tank B. At that time, tank A had a total of 46 gallons of water.
Select the equation that represents the given situation and find the number of gallons of water in tank B.
A. 4x + 2 = 46,21 gallons
B. 2x + 4 = 46; 21 gallons
C. 2x + 4 = 46, 11 gallons
D. 4x + 2 = 46, 11 gallons

Answer 1

D. 4x + 2 = 46, 11 gallons

Explanation:

First Part, Tank A = y , Tank B = x

y = 4x + 2

Second Part, Tank A = 46 so y = 46

46 = 4x + 2

44 = 4x

11 = x

Therefore, Tank B = 11 gallons
