Answer:
6x
Step-by-step explanation:
7x - x
X by itself is the same thing as 1x.
So, if we rewrite the equation using 1x instead of just x:
7x - 1x
Now, we can subtract like we normally would.
7x - 1x = 6x
Answer:
No.
Step-by-step explanation:
There are two different ways to do this - solve for x in the given equation or substitute the value for x and see if you get a true statement.
3x + 7 = 13 subtract 7 from both sides
3x = 6 divide by 3 on both sides
x = 2
3(3) + 7 = 13
9 + 7 = 13
16 ≠ 13
Therefore, x = 3 is not a solution for 3x + 7 = 13.

Answer:
x = 6
Step-by-step explanation:
• ∠THX and ∠XHV have a common side HX and a common vertex H
This means they are two adjacent angles.
Then
m∠THX + m∠XHV = m∠THV
Then
53 + 12x−9 = 16x + 20
<u>Solving the equation</u>:
53 + 12x−9 = 16x + 20
⇔ (53 − 9) + 12x = 16x + 20
⇔ 44 = 16x - 12x+ 20
⇔ 44 - 20 = 4x
⇔ 24 = 4x
