Simplify the expression: 2(x + 5) - 3.

To simplify the expression ( 2(x + 5) - 3 ), we start by distributing the 2 to both terms inside the parentheses. This means we multiply 2 by ( x ) and then by 5:

[ 2(x + 5) = 2x + 10

]

Next, we need to subtract 3 from the result of our distribution:

[ 2x + 10 - 3 ]

Now, we combine the constants (10 and -3):

[ 10 - 3 = 7 ]

Therefore, the expression simplifies to:

[ 2x + 7 ]

This shows that the correct simplified form of the original expression is ( 2x + 7 ).
