The expression once the left side of an equation is shown below. 3(x+1)+9 if the equation has no solution which expression can be written in the box on the other side of the equation a. 3(x+4) b. 2(x+6)+x c. 4(x-3)-x d. 3(x+1)+9

C. 4(x-3)-x

All of the given expressions are equivalent to 3x+12 except selection C. Using that in your equation makes it be ...

... 3(x +1) +9 = 4(x -3) -x

... 3x +12 = 3x -12

... 12 = -12 . . . . . false

There is no value of x that will make this true, hence NO SOLUTION.

Comment on the other choices

3x+12 = 3x+12 has an infinite number of solutions, as any value of x will make this true.
