The Given equations are 2 x+3 y=0 .......(1)
x+2 y-1 =0.........(2)
<u>Step 2:-</u>
Solving<u> </u>both equations by using substitution method
multiply equation (2) with number '2' ,
2 x+4 y-2=0.......(3)
subtracting the equations (1) and (3) and cancelled 'x' terms
we get
<u>Step 3:</u>-
substitute y= 2 in equation (1) we get
<u>Final answer</u>:-
The solution of the given equations is (-3,2)
