first verify the question a or b ?
in either case the objective will be to isolate the term with the variable then divide by the coefficient of the variable.
when you have an equation whatever you do to one side also do to the other to maintain the balance
|dw:1433184144410:dw|d is actually attached to the 2
1/2d+4=7d-4 Ok so the first step is to move all the variables to one side. So we subtract 1/2d from both sides. 1/2d-1/2d+4= 7d-1/2d-4 do you get that part?
what happens to the 8d?
there is no 8d. your problem was: 1/2d+4=7d-4
The equation is actually 1/2d+4=7/8d-4. I forgot to add the 8d when I posted the question.
oh 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=7/8d-4. You get that so far?
ok so now we want to move the variables all to the same side so we do: 4/8d-4/8d+4=7/8d-4/8d-4. you get that part?
so it would look like 4=7/8d-4/8d-4.
correct :) so now we do 7/8d-4/8d= 3/8d so now the equation is 4= 3/8d-4 then we add 4 to both sides: 4+4= 3/8d. you get that part?
ok 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?
I really hope you understand the importance of posting all of the original problem clearly.
triciaal, yes I do. I thought I had but then I saw that I had forgotten to put in the 8d.
hockeychick23, when I multiplied 8/1 times 8/3 I got 21 1/3
correct :) d= 21 1/3 is your final answer
thank you :)
where did the 3 come from?
your wrong triciaal its 64/3 which is the same thing as 21 1/3
everything fine until 8 = 3/8d
they got it right already
How would I get the 64/3?
if it were |dw:1433188598528:dw|
8/1*8/3 so you multiply 8*8 and 1*3 giving you 64/3
@hockeychick23 your process is correct but that is not what you had above see the difference with the location of the variable
@vchenoweth22 the process is correct isolate the terms with the variable simplify divide by the coefficient (same as multiply by the reciprocal)
