Explanation:
The equation is [tex]3x=36[/tex]
Frida started to solve the equation by adding 3 to both sides.
Thus, the equation becomes,
[tex]3x+3=39[/tex]
This will not solve the equation.
To solve the equation [tex]3x=36[/tex], we need to divide both sides of the equation by 3.
Thus, the equation becomes,
[tex]\frac{3x}{3} =\frac{36}{3}[/tex]
Dividing we get,
[tex]x=12[/tex]
Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.
Thus, to solve the equation [tex]3x=36[/tex] Frida needs to divide both sides of the equation by 3.
