What is the value of x in the equation 2 times open paren x minus 3 close paren plus 9 is equal to 3 times open paren x plus 1 close paren plus x ?

Distribute on both sides: 2(x − 3) + 9 becomes 2x + 3, and 3(x + 1) + x becomes 4x + 3. Then 2x + 3 = 4x + 3, so subtracting 3 gives 2x = 4x. Subtract 2x from both sides to get x = 0, which is choice C.
