Y = x + 7
<span>y = -2x - 11
x + 7 = -2x - 11
3x + 7 = -11
3x = -18
x = -6
The x-coordinate of the solution is -6.
I have attached a graph of the two equations since the question really wanted you to graph it and then find the answer.</span>

Answer:
Step-by-step explanation:
First, add two to both sides to get
There are two ways to solve this from here
- Think about what power you would have to raise 9 to to get to 27.
= 3 and
. So, multiplying the powers (because it is a power to a power) you get
. This means that
or x =
.
- Take the log of both sides.
This gives us
