" 7."(2x)/(3)=18

Solve the equation. 1.6 = y/15 , (2x)/3=18 , 7x-9=16

Solve : (7 + x)/(5) - (2x - y)/(4) = 3y - 5 (5y - 7)/(2) + (4x - 3)/(6) = 18 - 5x

-3 le 4 - (7x)/(2) le 18

Solve the inequalities : ,-3<=4-(7x)/(2)<=18

Decide whether the values given against each equation are the solutions of that equation or not : (18-2x)/(x-4)=4/3 , x = 0, 7, -7

Show that the function f(x)=4x^(3)-18x^(2)+27x7 is always increasing on R

Solve the given equations: x +y +z=0 x^(3) + y^(3) +z^(3)=18 x^(7) + y^(7) + z^(7) = 2058 where x,y,z in R

If tan""(2pi)/(18),x andtan""(7pi)/(18) are in A.P. and tan""(2pi)/(18),t and tan""(5n)/(18) are in A.P. then the value of x/y will be
