Zapisz wyrażenie w jak najprostszej postaci. a) (11+2x)+(6x-9)-(-2x+13) b) (-5m-6t+4)+(-5t-6m-4) c)-(-2xy-x+4y)-(6x+3y-5xy) d) -(-5m+1)-(-2m-3)+(-6m+8)

a) (11+2x)+(6x-9)-(-2x+13)= =11+2x+6x-9+2x-13= =-11+10x b) (-5m-6t+4)+(-5t-6m-4)= =-5m-6t+4-5t-6m-4= =-11m-11t c)-(-2xy-x+4y)-(6x+3y-5xy)= =2xy+x-4y-6x-3y+5xy= =7xy-5x-7y d) -(-5m+1)-(-2m-3)+(-6m+8)= =5m-1+2m+3-6m+8= =m+10
