Sprowadź wyrażenie do najprostszej postaci (-5a plus b-3)-(2a-3b plus 5)-(4a-b-8)

(-5a + b-3)-(2a-3b + 5)-(4a-b-8) = -5a + b - 3 - 2a + 3b - 5 - 4a + b + 8 = - 11a + 5b

(-5a plus b-3)-(2a-3b plus 5)-(4a-b-8)= -5a+b-3-2a+3b-5-4a+b+8= -11a+5b

( -5a + b - 3 )-( 2a - 3b + 5 ) - ( 4a - b - 8 ) = -5a + b - 3 - 2a + 3b - 5 - 4a + b + 8 = -11a + 5b Pozdrawiam :)
