Answer:
x = 0
Explanation:
Given the expression;
[tex]2x\text{ + 9 = 9}[/tex]You are to find the value of x that will make the equation true;
First you need to subtract 9 from both sides;
[tex]\begin{gathered} 2x\text{ +9-9 = 9-9} \\ 2x\text{ = 0} \end{gathered}[/tex]Then you divide both sides of the equation by 2;
[tex]\begin{gathered} \frac{2x}{2\text{ }}=\frac{0}{2} \\ x=0 \end{gathered}[/tex]Hence the value of x is 0
