Answer:
x=-2 or x=7
Step-by-step explanation:
subtract 14 on both sides
factor the left side of the equation
find what minus what equals 0
then you get x=-2 and x=7
3x - 13 = 8
<em><u>Add 13 to both sides.</u></em>
3x = 21
<em><u>Divide both sides by 3.</u></em>
x = 7
Now that we have the value of x we can solve x - 4.
7 - 4 = 3
The value of x is 7, and the answer to the second expression is 3.
