  1. combine terms

    .02x + .06 - 8x + 12 =

    -7.92x  = -12

           x = 12/7.92

           x =  1.51


  2. .02(x+3)-4(2x-3)=3.4

    .02x+.06-8x+12=3.4

    -7.98x+12.06=3.4

    -7.98x=-8.66

    x=1.085...

  3. Add like terms together:

    (.02 - 8) x + (.06 + 12) = 3.4

    - 7.8 x + 12.06 = 3.4

    7.8x = 12.06 -3.4 = 8.66

    x = 1.1102564

  4. 2/100=1/50

    x/50+3x/50=4x/50 is first part

    -8x+12 is second part

    4x/50-8x+12=3,4

    (4x-400x+600)/50=3,4

    (4x-400x+600)=50*3,4

    4x-400x+600=170

    -396x=-430

    x=396/430
