My bad its x + 7/4x = 66

>>6949453
x + 7/4x = 66
x * 4x + 7 = 66 * 4x
4xx - 264x + 7 = 0
x = (264 (+-) sqrt(264*264 - 4*4*7)) / 8
There you go OP, have a nice day!

here
anon of >>6949481
why didn't you just do (7/4+1)x=66

>>6949448
>x + 7/4 = 66
>x = 66 - 7/4
wow, that was hard!

>>6949504
because muh parenthesis
7/4x =/= 7x/4

>>6949513
oh, well shit then carry on

>>6949453
is it x+ (7/4)x = 66
or x+ 7/(4x) = 66?

First way, x= (4/4)x so 11x/4 = 66 and x = (66*4)/11

Second way 4x^2-264x+7 = 0, use quadratic formula.

This board is not for homework help.
Also, are you 12 or just retarded?

Enjoy being an undergrad.

It excludes negative hearts from its domain, which is pretty useful if you ask me.

>>6949448
set brackets to denote order of operations. interesting

>>6949453
x + 7/4x = 66
(7+4x^2)/4x = 66
7+4x^2 = 264x

4x^2 - 264x + 7 = 0
