In this Lecture you will go through following Topics: 1. Linear Equations i) Definition ii) Solving a Linear Equation in One Variable iii) Equations Involving Radicals but Reducible to Linear Form

Select a question from the list bellow to see the video of that Question directly (works best in Google Chrome Browser): 1. Solve the following equations (i) 2/3 x-1/2 x = x+1/6 (ii) (x-3)/3-(x-2)/2 = -1 (iii) 1/2 (x-1/6)+2/3 = 5/6+1/3 (1/2-3x) (iv) x+1/3 = 2(x-2/3)-6x (v) (5(x-3))/6-x = 1-x/9 (vi) x/(3x-6) = 2-(2x)/(x-2) (vii) (2x)/(2x+5) = 2/3-5/(4x+10) (viii) (2x)/(x-1)+1/3 = 5/6+2/(x-1) (ix) 2/(x^2-1)-1/(x+1) = 1/(x+1) (x) 2/(3x+6) = 1/6-1/(2x+4) Q. 2: Solve each equation and check for extraneous solution, if any.
