4 × ( x + 4 ) = 3 × ( 3 + 5 )
4 × ( x + 4 ) = 3 × 8
Divide both sides by 4
x + 4 = 3 × 2
x + 4 = 6
Subtract both sides 4
x = 2

Answer:
C
Step-by-step explanation:
Add 10x to both sides:
-10x - 135 = 117 + 2x
-10x - 135 + 10x = 117 + 2x + 10x
-135 = 117 + 12x
Subtract 117 from both sides:
-135 - 117 = 117 + 12x - 117
-252 = 12x
Divide both sides by 12:

-21 = x
So the answer is C.
Hope this helps!

Answer:
The given equation cannot be written in slope intercept form
Step-by-step explanation:
we know that

Is the equation of the line in slope intercept form
where
m is the slope
b is the y-intercept
In this problem we have

This is a vertical line (parallel to the y-axis)
The slope is undefined
therefore
The given equation cannot be written in slope intercept form
