Question 199527
first answer is correct.
remember ()() means multiply
x means multiply
* means multiply
a) 4y-4=6+2y
     2y=10
      y=5
b) 2/3-x/6=1
   4/6-x/6=1
       4-x=1
        -x=1-4
         x=-1+4
         x=3
c) 0.2(x-4)=3
   0.2x-0.8=3
        .2x=3+0.8
        .2x=3.8
          x=19
Just to let you know, it isn't as easy as it once was, I am 69 and still tutor GED students just to keep fresh.
