Pq
because they constant is the multiple of the last digit of each factor
Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

Now, we can substitute this into the first equation. Therefore:

1 and a fourth because 3 3/4 devided by three equals 1 1/4

÷

First, apply this following rule:

÷

×


×
Second, apply this following rule:

×

Third, multiply 1 × 6 to get 6 and 6 × 2 to get 12.
Fourth, find the GCF of 6 and 12.
Factors of 6: 1, 2, 3, 6
Factors of 12: 1, 2, 3, 4, 6, 12
The GCF is 6.
Fifth, divide the numerator by the GCF.

÷
Sixth, divide the denominator by the GCF.

÷
Seventh, collect the new numerator and new denominator.

Answer as fraction:
