Answer:

x = 3, y= -1

Step-by-step explanation:

12x-y=37

-5x-y=-14

12x-y=37

-1(-5x-y)=-1(-14)

12x-y+5x+y=37+14

17x = 51

(17x)/17 = 51/17

x = 3

12(3)-y=37

36-y=37

-y = 1

y = -1

Similfy 1/2 (30x + 4y - 14 ) +1/4 (16x - 28y + 4)
Hoochie [10]

Answer:

19x - 5y - 6

Hope this helped

Step-by-step explanation:

You start by simplifying each expression, you will be distributing the number outside the parentheses  on each number inside the parentheses

1/2(30x+4y-14)

1/4(16x -28 +4)

leaving you with

15x + 2y - 7 + 4x - 7y + 1

combine the x's y's and the singular numbers

19x - 5y - 6
