Question

The following is a system of two linear equations in two variables that is consistent and dependent:
-x + y = 1
3x +3y = -3
Give three (3) ordered pairs that are solutions to the system

Answer 1

Answer:

x=1 y=0

Step-by-step explanation:

Here,

-x+y=1 x3

-3x+3y=3............(1)

3x+3y=-3..........(2)

We solve simultaneously,....

'adding eqn(1)+ eqn (2).

-3x+3y=3

+ 3x+3y= -3

-----------------------

0+6y=0

y=0x6

[y=0]

We put [y=0] in eqn (2)

3x+3y=3

3x+3x0=3

3x+0=3

3x=3

x=-3

3

[x= -1]

:.x= -1 , y=0
