1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?
[ Triple the quantity of a number “n” ] 3n
[ plus 4 ] + 4
[ equals 27 ] = 27
[ all together ] <u>3n + 4 = 27</u>
<u />
<u>Solving:</u>
[ given ] 3n + 4 = 27
[ subtract 4 from both sides ] 3n = 23
[ divide both sides by 3 ] n = 7
2:Seventeen equals seven less than three times a number “n” what would the expression look like?
[ Seventeen equals ] 17 =
[ seven less than ] - 7
[ three times a number “n” ] 3n
[ all together ] <u>17 = 3n - 7</u>
<u />
<u>Solving:</u>
[ given ] 17 = 3n - 7
[ add 7 to both sides ] 24 = 3n
[ divide both sides by 3 ] 8 = n
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Set denominator to zero and solve for x.
x^2 - x - 12 = 0
Factor.
(x - 4)(x + 3) = 0
Solve each factor for x.
x - 4 = 0
x = 4
x + 3 = 0
x = -3
Answer:
The domain is ALL REAL NUMBERS except for x = 4 and x = -3.
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
-------------------------------------
2x + y = -3 <em>subtract 2x from both sides</em>
y = -2x - 3
-2y = 6 + 4x
-2y = 4x + 6 <em>divide both sides by (-2)</em>
y = -2x - 3
We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions
x ∈ R
y = -2x - 3
