Step-by-step explanation:
<u>Step 1: Define equation</u>
-12(a - 2) = -50
<u>Step 2: Solve for </u><em><u>a</u></em>
- Divide -12 on both sides: a - 2 = 25/6
- Add 2 on both sides: a = 37/6
<u>Step 3: Check</u>
<em>Plug in a into the original equation to verify it's a solution.</em>
- Substitute in <em>a</em>: -12(37/6 - 2) = -50
- Subtract: -12(25/6) = -50
- Multiply: -50 = -50
Here we see that -50 does indeed equal -50.
∴ a = 37/6 is a solution of the equation.

Answer:
Parametric Equation of a Line
Step-by-step explanation:
A line, parallel to vector (a,b,c) passing through point P (x1,y1,z1) is represented by parametric equations
x = x1+ at
y = y1 + bt
z = z1 + ct
