sederhanakan bentuk bentuk berikut

a.7x+3x=10x
b.5a+3b+a-5b=6a-2b
c.(-3y²+2y-4)+(2y²-3y+5)
=-3y²+2y-4+2y²-3y+5
=-3y²+2y²+2y-3y-4+5
=y²-y+1
d.(2p³+p-5)-(2p²+3p-4)
=2p³+p-5-2p²-3p+4
=2p³-2p²+p-3p-5+4
=2p³-2p²-2p-1

a. 7x+3x=10x
b. 5a+3b+a-5b =5a+a+3b-5b =6a-2b
c. (-3y²+2y-4)+(2y²-3y+5) = -3y²+2y²+2y-3y-4+5 =-y²-y+1 (sama-sama dibagi -1) = y²+y-1
d. (2p³+p-5)-(2p²+3p-4)=2p³-2p²+p-3p-5+4 =2p³-2p²-2p-1
