Answer:
t = 
Step-by-step explanation:
First, you need to complete the -3 + 1 and then expand the brackets
-3 + 1 = -2
7t -2 - (-2) = -3(1 - 3t)
Now expant the -3(1 - 3t) bracket
-3 * 1 = -3
-3 * -3t = 9t
7t - 2 - -2 = 9t - 3
The two negatives turn positive:
7t - 2 + 2 = 9t - 3
7t = 9t - 3
Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:
3 = 9t - 7t
3 = 2t
Divide both sides by 2:
t = 
So the value of t is

Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.
squared distance from P(x,y) to focus F(2,2)
(x - 2)² + (y - 2)²
squared distance from P(x,y) to the directrix x=8.
(x-8)²
Those are equal in a parabola,
(x - 2)² + (y - 2)² = (x-8)²
x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64
y² - 4y - 46 = -12x
That's a sideways parabola,
x = -(y² - 4y - 46)/12
