Answer:
solution is x=3
Step-by-step explanation:
apply log property
log a- log b= log a/b
we have log on both sides
so we remove the log and make the arguments equal
solve for x, multiply whole equation by 3
now plug in 3 for x and check
solution is x=3
Answer:
the answer your looking for is 3
Step-by-step explanation:
Answer:a gallon
Step-by-step explanation:if you add cup by cup you can see that it is a gallon by adding them or putting it in a allon jug
Here is a graph with the equation you gave graphed on it.
So,
Let's translate this into mathematical form.
x - y = 9
x + 2y = 27
Elimination by Addition
Divide both sides of the second equation by 2
Add the two equations together
Multiply both sides by
Substitute
15 - y = 9
Subtract 15 from both sides
-y = -6
y = 6
Substitute
15 - 6 = 9
9 = 9 This checks.
15 + 2(6) = 27
Distribute
15 + 12 = 27
27 = 27 This also checks.
S = {(15,6)}
