Multiply out:
56s + 16 = -16s - 256
Put all s terms on one side and all non-s terms on the other side:
56s + 16s = -256 - 16
72s = -272
Divide by 72:
s = -272/72
s = -3.7777 or -3 7/9

8(7s + 2) = -4(4s + 64)
56s + 16 = -16s - 256
56s + 16s = -256 - 16
72s = -272
s = -272/72
s = -34/9
or
s = -(3 and 7/9)

8(7s + 2) = - 4(4s + 64)
56s + 16 = -16s - 256 (simplified)
72s + 16 = -256 (added 16s to each side)
72s = -272 (subtracted 16 from each side)
s = -3.777777778 (divided each side by 72 to get final answer)
Hope that helps!

8(7s+2) = -4(4s+64) distribute 8 through parenthesis
56s + 16 = -4(4s+64) distribute -4 through parenthesis
56s + 16 = -16s-256 subtract 16 from both sides
56s + 16(-16) = -16s - 256 (-16) simplify
56s = -16s - 288 add 16s to both sides
56s (+16s) = -16s (+16s) - 288 simplify
72s = -288 divide both sides by 72 to isolate the variable
72s/72 = -288/72 simplify
s = -64 --> --> --> YOUR ANSWER
-------------------------------------------------------
to check you just put your s value (which is -64) in the equation every time there is a "s"

s = 6 or ( 56s + 16 = 16s + 256 )

56s + 16 = - 16s - 256
72s = - 272
s = - 272 / 16 = - 68 / 4 = - 17

56s+2=-16s+64
56s+16s=64-2
40s=62
40s/40=62/40
s=1.5 or31/20

distribute the 8 and the 4 outside the parenthesis and then combine like terms. i think. algebra sucks.
