jhonyy9 · Answer

write the proportionalitie of coresponding sides 

do you know it how ?

jhonyy9 · Answer

16      x-1
--- = ----
12        6

can continue it to solve for x ?

jhonyy9 · Answer

bc. denominator common is 12 so multiplie the (x-1) by 2 and will get 

16 =2(x-1)

so now can you solve it for x ?

brooklynnfaith98 · Answer

how do you slove the first equation that you gave me.. ?

jhonyy9 · Answer

2(x-1)= ?

jhonyy9 · Answer

=2x-2
yes ?

jhonyy9 · Answer

so than 

16 =2x-2   add to both sides 2 and will get 

16+2=2x
18=2x  divide both sides by 2 and get 

9 = x 

yes ?

jhonyy9 · Answer

do you understand it sure ?

brooklynnfaith98 · Answer

yes , I get how to slove it now but I don't know to take the first equation that you gave me and make it what you put it into ..?

jhonyy9 · Answer

brook are you here please ?

jhonyy9 · Answer

so i think that you dont know what mean write the proportionalitie of correspondonig sides - yes ?

brooklynnfaith98 · Answer

yes
