The new equation is [tex]x+16=25[/tex]
Explanation:
The equation is [tex]x=9[/tex]
We need to determine the new equation by adding 16 to both sides of the equation.
Hence, we shall increase both sides of the equation [tex]x=9[/tex] by 16, we get,
[tex]x+16=9+16[/tex]
Adding, we get,
[tex]x+16=25[/tex]
Hence, the new equation is [tex]x+16=25[/tex]
