steve can you explain step by step please
8x=5y and 3y=14z then 12x= how many z's

math steve 
Steve
you know that 8x = 5y
you know that 3y=14z
since 5 = (5/3)*3, 5y = (5/3)*(3y) so,
5y = (5/3)(3y) = (5/3)(14z) = (70/3)z
now you have 5y, which is the same as 8x. You want 12x.
since 12 = (3/2)*8, 12x = (3/2)*8x.
12x = (3/2)(8x) = (3/2)(5y) = (3/2)(70/3)z = (70/2)z = 35z
Don't know how I can clear it up any more.

3 y = 14 z
so
y = (14/3) z
8 x = 5 (14/3) z
x = (5/8)(14/3)z
12 x = 12(5/8)(14/3)z = 35 z
