Answer:
2x+8=4x+6
8-6=4x-2x
2=2x
2x=2
x=2/2
x=1
Step-by-step explanation:

LCM = 5 × 3 × 3 × 7 × 2 × 2 × 5
LCM = 6300
<u>Hence, the LCM of 315 , 420 , 525 is 6300</u>
Equation
-4x + 16 = -116
solve for x
-4x + 16 = -116
subtract 16 to both sides
-4x + 16 - 16 = -116 - 16
simplify
-4x = -132
divide -4 to both sides
-4x/-4 = -132/-4
simplify
x = 33
answer: the number is 33
In the given image,

<h3>Matrix notation</h3>
From the question, we are to determine which entry in the given matrix represents 
NOTE: For any entry denoted as
, it represents the entry in the <em>m</em>-th row and <em>n</em>-th column.
Thus,
represents the entry in the 2nd row and 3rd column.
In the given image, the entry in the 2nd row and 3rd column is 5.
Hence, in the given image,
is 5. The correct option is the first option 5
