6x+18=h (3x+9) what value the constant h in the equation shown below will result in a infinite number of solutions

For there to be an infinite number of solutions, the quantity on the left side of the equation must be the same as on the right.

First, distribute the equation to get

6x + 18 = 3xh + 9h

If h = 2, the equation on the right would also be 6x + 18 which would yield the same equation and hence an infinite number of solutions

So the answer is h = 2
