Answer:
The solution of given system of equations is (-1,1).
Step-by-step explanation:
The given equation are
..... (1)
..... (2)
Add both equations.


Subtract both sides by 2.


Divide both sides by 2.

Put this value in equation 1.

Add 1 on the both sides.


Therefore the solution of given system of equations is (-1,1).
Solution of system of equation graphically.
Plot both lines on the graph.
Put x=0, the find the y-intercept of both equations.

Put x=1, the find the y-intercept of both equations.

Therefore first line passing through the points (0,0) and (1,-1).
Put x=0, the find the y-intercept of both equations.

Similarly, put y=0 in second equation.

y-intercept of second equation is (-2,0).
Therefore second line passing through the points (0,2) and (-2,0).
From the graph it is noticed that both the line intersect on the point (-1,1), therefore solution of given system of equations is (-1,1).
