Answer

The solution is $\frac{17}{2}$.

Work Step by Step

4(x-7)=6 4x-28=6 4x-28-6=6-6 4x-34=0 2(2x-17)=0 2x-17=0 2x-17+17=0+17 2x=17 $\frac{2x}{2}$=$\frac{17}{2}$ x=$\frac{17}{2}$ The solution is $\frac{17}{2}$. Check Let x= $\frac{17}{2}$ 4(x-7)=6 4( $\frac{17}{2}$ -7)=6 4*$\frac{17}{2}$-4*7=6 2*17-28=6 34-28=6 6=6
