It would be A. 9-2n. I Hope this helped.
Step-by-step explanation:
Expand the bracket
12s + 8 = 4s - 2
collect like terms
12s - 4s = -2 - 8
8s = -10
divide by the co-efficient of s
S = - 5/4 or - 1.25
Hope this helps, pls like and follow :,-):-)
Number 3 i would say i think it is
Answer:
I can not see please take other picture
Answer:
k = 7
Step-by-step explanation:
Step 1: Write equation
-18 = 5 - (6k - 19)
Step 2: Solve for <em>k</em>
<u>Distribute negative:</u> -18 = 5 - 6k + 19
<u>Combine like terms:</u> -18 = -6k + 24
<u>Subtract 24 on both sides:</u> -42 = -6k
<u>Divide both sides by -6:</u> k = 7
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-18 = 5 - (6(7) - 19)
-18 = 5 - (42 - 19)
-18 = 5 - 23
-18 = -18
