Answer:
x = 19
Step-by-step explanation:
To find the value of x, you set the equations as equal to each other:

Then you simplify:

Answer:
C
Step-by-step explanation:
The quotient is 18
Answer:
If you are reffering to GCF then the GCF would be explained like this
Find the prime factorization of 18
18 = 2 × 3 × 3
Find the prime factorization of 60
60 = 2 × 2 × 3 × 5
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3
GCF = 6
The answer is -4 because -4 times -3 equals -12
(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138
