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
