Answer 1

Answer:

x = $-\frac{1}{3}$, y = 2

Step-by-step explanation:

3x + 3y - 7 = 12x + y

6y - 12x - 1 = -45x

(3x - 12x) + (3y - y) = 7

(-12x + 45x) + 6y = 1

-3(-9x + 2y = 7)

33x + 6y = 1

27x - 6y = -21

33x + 6y = 1

60x = -20 -> x = -20/60 = -1/3

-9x + 2y = 7 -> y = $\frac{7+9x}{2}$ = $\frac{7+9*-\frac{1}{3}}{2}$ = 2
