Solve the following system of equations: (x)/(2)+y=0.8,(7)/(x+(y)/(2))=10

solve using ellimination method (x)/(2)+y=0.8 and (7)/(x)+(y)/(2)=10

Solve the following system of equations: x/2+y=0. 8 ,\ \ 7/(x+y/2)=10

The circles whose equations are x^(2)+y^(2)+10x-2y+22=0 and x^(2)+y^(2)+2x-8y+8=0 touch each other. The circle which touch both circles at, the point of contact and passing through (0,0) is, 1) 9(x^(2)+y^(2))-15x-20y=0, 2) 5(x^(2)+y^(2))-18x-80y=0 3) 7(x^(2)+y^(2))-18x-80y=0, 4) x^(2)+y^(2)-9x-40y=0 ]]

Find the equation of the common tangent of the following circles at their point of contact x^(2)+y^(2)=10x-2y+22=0, x^(2)+y^(2)+2x=8y+8=0

The two circles x^(2)+y^(2)-2x-2y-7=0 and 3(x^(2)+y^(2))-8x+29y=0

The two circles x^(2)+y^(2)-2x-2y-7=0 and 3(x^(2)+y^(2))-8x+29y=0

If the circles x^(2)+y^(2)+10x+8y+c=0 and x^(2)+y^(2)-10x-8y+c=0 cut onbogonally,then the value of 'C'' is
