Question

-5/7×(s+-4/7)=-5/7×2/5+t×-4/7

Answer 1

Hi ,

***********************

distributive property :

a × ( b + c ) = a × b + a × c


********************************

Now ,

( -5/7 ) × [ s + ( - 4/7 ) ] = ( -5/7 )× 2/7 + t × ( - 4/7 )

( -5/7 )s + ( -5/7 )(-4/7 ) = ( -5/7)( 2/7 ) + t ( - 4/7 )

compare both sides of the equation ,

s = 2/7 ,

t = - 5/7

I hope this helps you.
