Answer:

(-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:

(-0.5, 1)

Step-by-step 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
