Solve the simultaneous equations. You must show all your working to find x and y. 1/2x -3y = 9 5x y + y = 28

dedylja [7]

Answer:

$\huge\boxed{x = 6 , y = -2}$

Step-by-step explanation:

$\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)$

Taking equation (1)

$\sf \frac{1}{2} x -3 y=9$

Multiplying both sides by 2

$\sf x-6y = 18$

Adding 6y to both sides

$\sf x = 18+6y$

Putting this in (2)

5(18+6y) + y = 28

90 + 30y+y = 28

31y+90-28 = 0

31 y + 62 = 0

31y = -62

Dividing both sides by 31

y = -2

Now,

x = 18 + 6y

x = 18+6(-2)

x = 18-12

x = 6
