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.
