A jawabanya gitu doang g tau
A.) 4 ( x - 2y ) - ( 2x - 9y) =
4 ( 5 - 2•(-3) ) - ( 2•5 - 9•(-3) ) =
4 ( 5 - (-6) ) - ( 10 - (-27) ) =
4 (11) - (37) = 44 - 37 = 7
C.) ( x + 7y ) + ( 4x - 3y ) =
( 5 + 7•(-3) ) + ( 4•5 - 3•(-3) ) =
( 5 + (-21) ) + ( 20 - (-9) ) =
-16 + 29 = 13
Penjelasan dengan langkah-langkah:
maaf kalo salah dan cmn segini saja
