Find equivalent expressions for the given expressions. a. 5/6(x - 6) + 1/6 (3 - x) b. (y + 7)4 + 8 - 5y show work

SOLUTION:

Question A -

= 5 / [ 6 ( x - 6 ) ] + 1 / [ 6 ( 3 - x ) ]
= ( 5 / 6 ) ( x - 6 ) + ( 1 / 6 ) ( 3 - x )
= ( 5 / 6 )x - 5 + ( 1 / 2 ) - ( 1 / 6 )x
= ( 4 / 6 )x - ( 9 / 2 )

Question B -

= ( y + 7 ) 4 + 8 - 5y
= 4y + 28 + 8 - 5y
= - y + 36
= 36 - y

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
