Best ResponseYou've already chosen the best response.0in either case the objective will be to isolate the term with the variable then divide by the coefficient of the variable.

Best ResponseYou've already chosen the best response.0when you have an equation whatever you do to one side also do to the other to maintain the balance

Best ResponseYou've already chosen the best response.01/2d+4=7d4 Ok so the first step is to move all the variables to one side. So we subtract 1/2d from both sides. 1/2d1/2d+4= 7d1/2d4 do you get that part?

Best ResponseYou've already chosen the best response.0what happens to the 8d?

Best ResponseYou've already chosen the best response.0there is no 8d. your problem was: 1/2d+4=7d4

Best ResponseYou've already chosen the best response.0The equation is actually 1/2d+4=7/8d4. I forgot to add the 8d when I posted the question.

Best ResponseYou've already chosen the best response.0oh ok no problem, so first lets make the variables numbers have the same denominator, so 1/2=4/8. so your equation will then look like this: 4/8d+4=7/8d4. You get that so far?

hockeychick23

Best ResponseYou've already chosen the best response.0ok so now we want to move the variables all to the same side so we do: 4/8d4/8d+4=7/8d4/8d4. you get that part?

Best ResponseYou've already chosen the best response.0so it would look like 4=7/8d4/8d4.

Best ResponseYou've already chosen the best response.0correct :) so now we do 7/8d4/8d= 3/8d so now the equation is 4= 3/8d4 then we add 4 to both sides: 4+4= 3/8d. you get that part?

Best ResponseYou've already chosen the best response.0ok so 8= 3/8d now we multiply the entire equation by 8/3 because it is the inverse of 3/8. 8/1*8/3=3/8*8/3d Do you get that part?

Best ResponseYou've already chosen the best response.0triciaal, yes I do. I thought I had but then I saw that I had forgotten to put in the 8d.

Best ResponseYou've already chosen the best response.0hockeychick23, when I multiplied 8/1 times 8/3 I got 21 1/3

Best ResponseYou've already chosen the best response.0correct :) d= 21 1/3 is your final answer

Best ResponseYou've already chosen the best response.0your wrong triciaal its 64/3 which is the same thing as 21 1/3

Best ResponseYou've already chosen the best response.08/1*8/3 so you multiply 8*8 and 1*3 giving you 64/3

Best ResponseYou've already chosen the best response.0@hockeychick23 your process is correct but that is not what you had above see the difference with the location of the variable

Best ResponseYou've already chosen the best response.0@vchenoweth22 the process is correct isolate the terms with the variable simplify divide by the coefficient (same as multiply by the reciprocal)
