Answer:
-2x - 8
Step-by-step explanation:
Combine like terms
-5x - 7x = -2
Therfore you have
-2x - 8
The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Given that x + 8 = 15
Hence:
x + 8 - 8 = 15 - 8 (subtraction property of inequality)
x = 7
The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15

Because they all go into 100 easily. for example 10*10=100 5*20=100
The illegal values of b are when the denominator equals 0.
So, gives you (b-4)(b+2)=0
Therefore, b=4 and b=-2, which is answer A.
