Solve this system of linear equation. separate the x- and y-values with comma. 4x+9y =-3 8x+12y=12

(x,y)= (-3,1)

Step-by-step explanation:

4x + 9y = -3  => eq(i)

8x + 12y = 12  => eq(ii)

We need to solve these equations to find the values of x and y.

Multiply eq (i) with 2 and then subtract both equations

8x + 18y = -6  

8x + 12y = 12

-     -          -

6y = -18

y= -18/6

y = -3

Putting value of y in eq(i)

4x + 9y = -3

x = -3

4(-3) + 9y = -3

-12 + 9y = -3

9y = -3+12

9y= 9

y= 9/9

y = 1

So, the value of x = -3 and y = 1

(x,y)= (-3,1)
