Verified Answer :

Step 1. Add 9 to both sides

\(-8(1+4h)=-17+9\)

Step 2. Simplify \(-17+9\) to \(-8\)

\(-8(1+4h)=-8\)

Step 3. Divide both sides by \(-8\)

\(1+4h=1\)

Step 4. Cancel 1 on both sides

\(4h=0\)
 Step 5. Divide both sides by 4

\(h=0\)

Done! :) Hope this helps! :)

To check \(-9-8(1+4h)=-17\) follow these steps below:

Step 1. Let h = 0

\(-9-8*(1+4*0)=-17\)

Step 2. Simplify 4 0 to 0

\(-9-8*(1+0)=-17\)

Step 3. Simplify 1 + 0 to 1

\(-9-8*1=-17\)

Step 4. 
Simplify  8
1 to 8

\(-9-8=-17\)

Step 5. 
Simplify -9 -8 to -17

\(-17=-17\)

Done! :)
 

-9 -8 (1+4h) = -17

-9 -8 - 32h = -17

-17 -32h = -17

-32h = 0

h = 0
