Answer:
x = 3
Explanation:
art with the equation: 3x + 7 = 16.
To isolate 3x on the left side, subtract 7 from both sides of the equation:
3x + 7 - 7 = 16 - 7
This simplifies to:
3x = 9
To solve for x, divide both sides by 3:
(3x) / 3 = 9 / 3
This simplifies to:
x = 3
So, the solution to the equation is x = 3.
