So for #1 It becomes

(4)(5) = 15x in the next step.

then continue to find X

**DrBob222**, Monday, September 14, 2009 at 11:28pmWhat do you mean by "understand"?

I can solve the first one for you.

4/15 = x/5

Cross mutliply.

5*4 = x*15

20=15x

x=20/15 = 4/3 = 1.333.

The second one needs some work.Is that x/3 = x+(10/6) or is it

x/3 = (x+10)/6

**Christy**, Tuesday, September 15, 2009 at 12:56amit is:

x/3 = x + 10/6

it would read as x over 3 = x plus 10 over 6

**Christy**, Tuesday, September 15, 2009 at 1:02amwhat i meant by not understanding is just that, i am lost with the numbers and letters together once i get someone to show me one i can do the rest. I can whip threw them if they are story problems but not just a line of letters and numbers.

Thanks for your help.
