cross multiply.
So for #1 It becomes
(4)(5) = 15x in the next step.
then continue to find X
What 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
it is:
x/3 = x + 10/6
it would read as x over 3 = x plus 10 over 6
what 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.
