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

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
