\text{Plug in 0 to h(x) and solve:}\\\\0=3x-7\\\\\text{Add 7 to both sides}\\\\7=3x\\\\\text{Divide both sides by 3}\\\\\frac{7}{3}=x\\\\\boxed{\frac{7}{3}=x}

h(x)=3x-7

And we are given that h(x)=0 and want to find the value of x. Set h(x) to 0 and we get the equation:

3x-7=0

Add both sides by 7

3x=7

Divide both sides by 3

x=\dfrac{7}{3}

This is the answer (as an improper fraction). Let me know if you need any clarifications, thanks!
