Answer:
Step-by-step explanation:
-x + y=-3
3x + 2y=9
=================
Rewrite the first equation to isolate x:
-x + y=-3, or
-x = -y - 3
x = y+3
------
Use the above value of x (y+3) in the second equation:
3x+2y=9
3(y+3)+2y=9
3y + 9 + 2y = 9
5y = 0
y = 0
---
Since y = 0
-x + y=-3
-x + 0 =-3
x = 3
(3,0)
=
One can also graph the two equations and find the point they intersect. Attached graph.
The required ordered pair of the system of the equations is (3, 0).
Given that,
-x + y = -3
3x + 2y = 9
To solve the system of the equation by elimination method and give correct ordered pair.
The equation is the relationship between variables and is represented as an example y =ax +b of a polynomial equation.
[tex]-x+y=-3[/tex] - - - - - -(1)
[tex]3x+2y=9[/tex] - - - - - - -(2)
Multiplying equations 1 by 3 then add to equation 2.
[tex]-3x+3y=-9\\+ 3x+2y=9\\\\[/tex]
[tex]5y = 0\\ y = 0[/tex]
Now putting the value of y in equation 1
-x + 0 = - 3
x = 3
Thus the required ordered pair of the system of the equations is (3, 0).
