Answer:
x = 2
Step-by-step explanation:
-3x - 6 = 8x + 16
8x - 3x = 16 - 6 (subtract like terms)
5x = 10 (divide by 5)
x = 2
Answer:
c. two real solutions
Step-by-step explanation:
x = -5 , x = 1.5
First, we want to find the GCF of 15 and 21, which is 3. Now we do 15 divided by 3 and 21 divided by 3, which gives us 5 and 7. To rewrite the expression, we take the GCF and put it on the outside of the parenthesis. Inside the parenthesis, we put 5 + 7. So it'll look like this:
3(5 + 7)
