Question 700732
2h + 2(2h+4) = 26
The distributive property says multiply each term inside the bracket by the term outside the brackets, then remove the brackets
2h + 4h + 8 = 26
Combine like terms
6h + 8 = 26
Subtract 8 from both sides
6h = 26 - 8
6h = 18
divide both sides by 6
h = 18/6
h = 3

Prove to yourself that this is true in the original problem
2h + 2(2h+4) = 26
replace h with 3
2(3) + 2(2(3) + 4) = 26
6 + 2(6+4) = 26
6 + 2(10) = 26
6 + 20 = 26; confirms the solution of  h = 3
