  1. 8.3- Solving equations of form ax+b = cx+d Obj: to solve equations with variables on both sides

  2. Example 1 3x+20 =x +40 -x -x 2x +20 = 40 -20 -20 2x = 20 2 2 x = 10

  3. Example 2 [ LCD Least Common Denominator ] ] [ 10 10 3x – 1 = 4x + 6 2 5 LCD 10(4)5 10(3)2 15x - 10 = 8x + 60 -8x -8x 7x – 10 = 60 +10 +10 7x= 70 x=10

  4. Example 3 ½x + 4 =10 2 b. [½x + 4= 10] • ½x = 6•2 • x= 12 1x +8 = 20 -8 -8 x =12
