Respuesta :

10(h+1)-4=76


Distributed property


10(h)+10(1)-4=76


10h+10-4=76


Subtract 10 minus 4


10h+6=76


Subtract 6 both sides


10h+6-6=76-6


10h=70


Divide 10 both sides


10h/10=70/10


H = 7


Answer is letter A

10 (h + 1) - 4 = 76

10h + 10 - 4 = 76  (distributive property)

10h + 6 = 76  (simplify)

        -6    -6  (inverse operation - subtract 6 from both sides)

10h = 70

10h/10 = 70/10  (inverse operation - divide both sides by 10)

h = 7

Check step:

10 (7 + 1) - 4 = 76

70 + 10 - 4 = 76

80 - 4 = 76

76 = 76

So, the answer is A.
