Answer:
x = 7
Step-by-step explanation:
<u>Distribute </u>-
12x − 66 + 15 = 3x + 12
<u>Combine Numbers and Variables</u> -
12x - 51 = 3x +12
<u>Get x on one side (isolate x)</u> -
9x - 51 = 12
9x = 63
<u>Divide 9</u> -
x =7
Is a problem solving method that uses that fact that any number or expression can be multiplied by one without changing it's value.

step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to

we have the ordered pairs
(3,-5) and (1,-9)
substitute the values



step 2
Find the equation in point slope form

Analyze two cases
<em>First case</em>
we have


substitute

<em>Second case</em>
we have


substitute

Note: The equation of the line in point slope form varies according to the point you choose, in contrast to the slope-intercept form
