Question

4x-y=-3 3Y-6x = 6
find ordered pair
​

Answer 1

(-60/11,111/11)

Step-by-step explanation:

Solving simultaneously, 4x - 3y=6 -3(6x + y=42) then it becomes, 4x - 3y=6

-18x - 3y= 126 subtracting the two equations, 22x= -120, x= -60/11 and y = 111/11

.

Answer 2

(-0.5, 1)

Explanation:

4x - y = -3 ----------------------(I)

-6x + 3y = 6 -------------------(II)

Multiply equation (I) by 3 and then add. So, y will be eliminated and you can find the value of x.

(I) * 3 12x - 3y = -9

(II) -6x + 3y = 6 {Now, add}

6x = -3

x = -3/6

x = - 0.5

Plug in x = -0.5 in equation(I)

4*(-0.5) - y = -3

- 2 - y = -3

-y = - 3 + 2

-y = -1

y = 1
