[tex]x=4[/tex]
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You need to apply the Distributive property on the left member of the equation:
[tex]2(x + 3) = x + 10\\ 2x+6=x+10[/tex]
2. Now, you must solve for [tex]x[/tex], as following:
[tex]2x-x=10-6\\ x=4[/tex]
