4.05p+14.40=4.50(p+3)
frist step is to multiple 4.50 to both p+3
so the equation is now
4.05p+14.40=4.50p+7.50
second you want to get on like things to one side does matter which (i will do both so you can see)
4.05p+14.40=4.50p+7.50
-4.50p -4.50p
the -4.50p cancels out on this way
-0.45p+14.40=7.50
-14.40 -14.40
the -14.40 cancels out on this way
-0.45p=-6.9
p=-6.9/-0.45
p=15.333333
4.05p+14.40=4.50p+7.50
-4.05p -4.05p
the -4.05p cancels out on this way
14.40=.45p+7.50
-7.50 -7.50
the -7.50 cancels out on this way
0.45p=6.9
p=6.9/0.45
p=15.333333
and there is your answer
Answer:
12
Step-by-step explanation:
Jim's currect age is x.
In 16 years, JIm will be x + 16.
In 4 years, Jim will be x + 4.
x + 16 = 3x
-2x = -16
x = 8
x + 4 = 8 + 4 = 12
Its a 1 gallon because 2 litera is really small
C would be equal to 0 in this equation
