Answer:
The correct answer is C.
Step-by-step explanation:
In order to solve this problem, you need to simplify the equation by using a natural log (ln). This will cancel out the e and make it easy to solve.
e^(2x + 5) = 4 ----> Take the ln
lne^(2x + 5) = ln(4) ------> Simplify
2x + 5 = ln(4) ------> Subtract 5
2x = ln(4) - 5 -----> Divide by 2
x = [ln(4) - 5]/2
This expression simplified would be 9a-18b-11
Answer:
x=-2 y=-6
Step-by-step explanation
5x+4=-3x-12
+3 +3x
8x+4=-12
-4 -4
8x=-16
÷8 ÷8
x=-2
Looking for y too, plug x into the original equation
5(-2)+4
-10+4
-6
y=-6
