7x = 63
Divide each side by 7 to isolate x
7x/7 = 63/7
x = 9
Answer:
The second one
Step-by-step explanation:
Additive identity is adding 0 to a number
First, list all the prime factors of both terms:
23x²: 1, 23, x, and x
6x: 1, 2, 3, and x
The two numbers share the prime factors 1 and x, so the GCF of 23x² and 6x is 1x, or x.
