Answer:

add 3 and divide by 2

Step-by-step explanation:

2x - 3 = 12

add 3 to both sides

2x - 3 +3 = 12 + 3

           2x = 15

Now divide bothsides by 2

\frac{2x}{2}=\frac{15}{2}\\\\x=7.5

12345678910 Using the greatest common factor for the terms, how can you write 80 + 32 as a product?
Romashka-Z-Leto [24]
Find the GCF of 80 and 32.  

I'd start by identifying possible integer factors of both 80 and 32:
80:  {1,2,4,5,8,10,16,20, 40, 80}

32:  {1, 2,4, 8, 16, 32}

Working backwards, we see that the first factor that is represented in both lists is 16.  Is 80 evenly divisible by 16?  Yes; the quotient is 5.
                  Is 32 evenly divisible by 16?  Yes; the quotient is 2.

You could writet 80 + 32 as 16(5 + 2).  This is a product equal to 112, just as 80 + 32 = 112.
