First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

$\frac{(x-7)(x+7)}{3(x + 7)}$

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:

$\frac{(x-7)}{3}$

Graph the linear equation. Find three

Karo-lina-s [1.5K]

-3y = -2x -6

Y= 2/3x + 2

When x= 3
Y= 2/3(3) + 2
Y= 2+2 = 4

(3,4)

When x= 6
Y=2/3(6)+2
Y= 4+2 = 6

(6,6)

When x= 12
Y= 2/3(12) + 2
Y= 8+2=10

(12,10)
