`(0.3+0.7x)/(x)=0.95`

Solve : 0.25+(1.95)/(x)=0.9

0.5x+(x)/(3)=0.25x+7

(0.7x-0.9)/(0.3x-0.7)=9

(2x+3)(3x-7)=0

Solve the following system of equations: 0. 5 x+0. 7 y=0. 74 ,\ \ \ \ 0. 3 x+0. 5 y=0. 5

{:(0.4x + 0.3y = 1.7),(0.7x - 0.2y = 0.8):}

{:(0.4x + 0.3y = 1.7),(0.7x - 0.2y = 0.8):}

If f(x)={[(sin7x)/(3x),x!=0 or m if x=0]} is continuous at x=0 then value of m is (a) 3/7 (b) 4/7 (c) 7/4 (d) 7/3

If f(x)={[(sin7x)/(3x),x!=0 or m if x=0]} is continuous at x=0 then value of m is (a) 3/7 (b) 4/7 (c) 7/4 (d) 7/3
