`x+5=12`

3 x + 5y = 12, 5x + 3y = 4 .

{:(3x + 5y = 12),(3x - 5y = - 18):}

5x + y = 135x + 5y = 12

Solve for x : (x)/(5) + (x)/(7) = 12

Solve , x/3 - x/8 = 5/12

Solve the following: (x^2 -5x+12)/(5x-12) = (x^2 -x-4)/(x+4)

Solve : 3/5 x+2=12/5

Find the value of x=> 5:x=3:12 .

The equation n s of the lines parallel to 5x-12 y+26=0 and at a distance of 4 units from it are: 5x-12 y-26=0 5x-12 y+26=0 5x-12 y-78=0 (d) 5x-12 y+78=0
