I’m gonna go with the second
First, rewrite the equation, separating the terms inside the parentheses and multiplying each by the term preceding the parenthesis, remembering that the product of two negatives is a positive, and likewise (later) with quotients:
(-3 * 12) + (-3 * (-m)) = (-1 * m) + (-1 * (-8))
-36 + 3m = -m + 8
Subtract 8 from both sides:
(-36 - 8) + 3m = -m + (8 - 8)
-44 + 3m = -m
Divide each term by -m:
(-44 / (-m)) + (3m / (-m)) = -m / (-m)
(44 / m) - 3 = 1
Add 3 to both sides:
(44 / m) - 3 + 3 = 1 + 3
44 / m = 4
(is the answer jumping out at you yet?) :-)
Multiply both sides by m:
(44 / m) * m = 4m
44 = 4m
Divide both sides by 4:
44 / 4 = m
11 = m
Verify by substituting for m in the original equation:
-3(12 - m) = -1(m - 8)
-3(12 - 11) = -1(11 - 8)
-3(1) = -1(3)
-3 = -3
Voila! That's it!
I think it is 6 and half you are supposed to multiply the scale ft and the model inches
