3y = 4
First, take the 3 and divide both sides by it.

Answer as fraction:

Answer as decimal: 1.3333
The problem in the picture would be
x^2+10x+21
-48 plugging in everything and using PEMDAS it should be -48
I believe x would equal to 30.
Since 6 * 3 =18, 10 * 3 = 30.
What you do to one side, you must do to the other.
Hope I helped!
Answer:
To reflect a graph, f(x) over the x-axis, you take -f(x).
So if f(x)=x^2, then -f(x) is -x^2.
Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.
