Solve each equation first and then choose the appropiate statement.

Equation 1


|5x-6|=-41

Since the absolute value of a number is always greater than 0 and -41<0, then this equation has no solutions.

Equation 2


\begin{gathered} |7x+13|=27 \\ \Rightarrow7x+13=\pm27 \\ \Rightarrow7x=\pm27-13 \\ \Rightarrow x=(\pm27-13)/(7) \\ \Rightarrow x_1=(27-13)/(7)=(14)/(7)=2 \\ \Rightarrow x_2=(-27-13)/(7)=(-40)/(7) \\ \therefore x_1=2,x_2=-(40)/(7) \end{gathered}

We can see that Equation 1 has 0 solutions and Equation 2 has 2 solutions.

Therefore, equation 2 has more solutions than equation 1.
