Answer:
(5,-2)
Step-by-step explanation:
Multiplying the first equation by 2 we get
2x+6y=-2
Subtracting the second equation we get
4y=-8
y=-2
Plugging y as -2 into the equation we get x=5
Answer:
(5, -2)
Step-by-step explanation:
x + 3y = −1
2x + 2y = 6 ⇒ x+y=3
Subtract second equation from the first one:
- x+3y=-1
- x+y=3
- 3y-y= -1 -3
- 2y= -4
- y= -2
- x= 3+2= 5
