Answer:
[tex]\frac{h-7}{10}=\frac{h+1}{2}[/tex]
[tex]\frac{h-7}{10}\times \:10=\frac{h+1}{2}\times \:10[/tex]
[tex]h-7=5\left(h+1\right)[/tex]
[tex]h-7=5h+5[/tex]
[tex]h-7+7=5h+5+7[/tex]
[tex]h=5h+12[/tex]
[tex]h-5h=5h+12-5h[/tex]
[tex]-4h=12[/tex]
[tex]\frac{-4h}{-4}=\frac{12}{-4}[/tex]
[tex]h=-3[/tex]
