Hi, a number line that goes up and down is called the y-axis. However, a number line that goes left and right is called the x-axis.
You will at 7 to both sides and then divide 2 on both sides to find x. :)
2x-7=3
+7=+7
—————
2x = 10

2 2
X = 5
Answer:
The value of x = 8
Step-by-step explanation:
For better understanding of the solution, see the attached figure of the diagram :
∠1 and ∠2 are alternate exterior angle and ∠3 is adjacent to ∠2
⇒ ∠1 = (4x + 28)°
⇒ ∠3 = (14x + 8)°
Now, ∠2 + ∠3 = 180° (Linear Pair)
⇒ ∠2 = 180 - 14x -8
⇒ ∠2 = 172 - 14x
Since the alternate exterior angles formed by the transversal between two parallel lines are equal in measure.
⇒ ∠1 = ∠2
⇒ (4x + 28)° = (172 - 14x)°
⇒ 18x = 144
⇒ x = 8
Therefore, ∠1 = ∠2 = 60° and ∠3 = 120°
Hence, The value of x = 8
24 is the answer to two ten's and four ones.
