Answer:
[tex]x = 15[/tex]
Step-by-step explanation:
The given equation is
[tex]2x = 15 + x[/tex]
This is a linear equation in x.
We solve for x by grouping similar terms.
Let us subtract x from both sides of the equation to get:
[tex]2x - x = 15 + x - x[/tex]
We simplify to get:
[tex]x= 15 + 0[/tex]
This implies that:
[tex]x = 15[/tex]
Therefore the correct solution is x=15.
