Question

check graphically whether the pair of equations x+y=8 and x-2y=2 is consistent. if so solve them graphically.also find the coordinates of the points where the two lines meet the y axis

Answer 1

it is consistent
frm eq 1 : x=8-y
substitute x vale in equation 2
so
8-y-2y=2
8-3y =2
3y=6
so
y=2
sub y vale in x
so
x=8-2=6
x=6
u can check whether it has solutions or not by equating the ratios of the coefficients of x^2 and and x and the constent term of the two equation
its there in ncert
i hope it helped u
