Answer:
x = -8
Step-by-step explanation:
(x + 8) = (2x + 16)
x + 8 = 2x + 16
take x from both sides 8 = x + 16
now take 16 from both sides -8 = x
x = -8
Answer:
x=-8
Step-by-step explanation:
To solve, you can factor the right side.
x+8 = 2(x+8)
Now if you try to divide by x+8, you will get this.
0 = 2
So this equation has no solutions - but wait!
You have to remember domain when dividing by an algebraic expression!
Since 0 is never equal to two, you must acknowledge that when dividing by an algebraic expression, the expression may be equivalent to zero. In this case, x+8 is equal to zero is x=-8, so the answer is x=-8.
Hopes this helps!
