Answer:
is this a question meant to evaluate you, such as a test, exam, quiz, or assessment?
Answer:
The answer is x = 2.
Step-by-step explanation:
7x + 3 = 2x + 13
5x + 3 = 13
5x = 10
x = 2
Take the natural log of both sides
ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3
ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative
