ayuda plissssss es para hoy​

Answer 1

Respuesta:

1.=4a+sb-4b

2.=4y+7z

3.=3yz-5y

4.=st+5s

Explicación paso a paso:

1.

(3a+sb)+(a-4b)

=3a+sb+a-4b

=3a+a+sb-4b

=4a+sb-4b

2.

(2y+z)+(2y+6z)

=2y+z+2y+6z

=2y+2y+z+6z

=4y+z+6z

=4y+7z

3.

(5yz+3y)-(2yz+8y)

=5yz+3y-(2yz+8y)

=5yz+3y-2yz+8y

=3yz-5y

4.

(6st-2s)-(5st-7s)

=6st-2s-(5st-7s)

=6st-2s-5st-7s

=st+5s

espero te ayude, dame coronita plis :)

Answer 2

Explicación paso a paso:

1) (3a +sb) +(a-4)

(3a+bs)+a-b

3a+bs+a-ab

4a+bs-4b

2) (2y+z)+(2y+6z)

2y+z +2y +6z

ay+7z

3) (5yz + 3y)-(2yz+8y)

5yz+3y-2y-8y

5y-7y

y(5z-7)

4) (6st-2s)-(5st-7s)

(2s(2t-1))-s(5t-7)

2s(3t-1)-s(5t-7)

s(2(3t-1)-(5t-7))

s(6t-2-5t+7)

s(t+5)
