Answer:
x = 1/21
Step-by-step explanation:
7 = 3/9x
Multiply both sides by 9x
7 x 9x = 3/9x x 9x
9x cancels out on the right side
63x = 3
Divide both sides by 63 to isolate x
63x/63 = 3/63
x = 1/21
C) (3, 2)
Solve for x and y, then plug in (x, y)
2y = 4, 2y/2 = 4/2, y = 2
-x = -3, -x/-1 = -3/-1, x = 3
