Answer:
x = 7
Step-by-step explanation:
Given
3x - 5 = 16 ( add 5 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Answer: X= 7
Explanation:
(you need to get x by its self)
Step 1- add the (-5) over to the 16
Because to get rid of a negative or minus sign you need to do the opposite which is addition.
You’ll get: 3x=21
Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division
You’ll get: X=21/3
Which is X=7
