Question

(x/7)+(y/8)= 10
solve for y; show steps if possible.(:

Answer 1

ok. u want y alone. start by moving the x/7 away from it. you should get it from there

Answer 2

so y/8=10-x/7?

Answer 3

then multiply by 8?

Answer 4

....sigh. 8x + 7y = 8*7*10

Answer 5

this is standard form. then just do y = [-8x - 560]/7
this is now more or less slope form

Answer 6

yes brit. no ronnc

Answer 7

80-8x/7=y

Answer 8

eh.. no way.
x/7 + y/8 = 10
so 8x/7 + y = 80
8x + 7y = 560
7y = -8x + 560 OR 560 -8x (same thing)
y = [-8x+560]/7 OR [560-8x]/7 (same thing again)..
you sleepy tutor?

Answer 9

you are correct ronnc, but you went the long way to scratch your butt.

Answer 10

true. but its depends how you want to do it. it can be arguable that I show steps better.

Answer 11

but you didnt simplify.

Answer 12

x+5=6/x
x(x+5)=6
x^2+5x=6
x^2+5x-6=0
now it is in quadratic equation form
x^2-x+6x-6=0
now takes the common
x(x-1)+6(x-1)=0
again (x-1) is common
(x-1)(x+6)=0
now the multiplication of two terms willbe 0 only when any one of them is 0
so
if x-1=0
then x=1
and if x+6=0
then x=-6
so ans is x=1,-6
are you satisfied ??
