5h - 7 = 2 (h+1) 
solve this 


Sagot :

[tex]5h-7=2(h+1) \\\\ 5h-7=2h+2 \\\\ 5h-2h=2+7 \\\\ 3h=9 \\\\ \boxed{h=\frac{9}{3}=3} [/tex]
[tex]5h-7=2(h+1)\\\\5h-7=2h+2\ \ \ \ \ |add\ 7\ to\ both\ sides\\\\5h=2h+9\ \ \ \ \ \ |subtract\ 2h\ from\ both\ sides\\\\3h=9\ \ \ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{h=3}[/tex]
