(1)若m-3n=2,则m+2-3n/2m-6n=?(2)若2a-3b=2,则4a-(6b+3)=?(1)若m-3n=2,则m+2-3n/2m-6n=?(2)若2a-3b=2,则4a-(6b+3)=?

(1)若m-3n=2,则m+2-3n/2m-6n=?(2)若2a-3b=2,则4a-(6b+3)=?
(1)若m-3n=2,则m+2-3n/2m-6n=?(2)若2a-3b=2,则4a-(6b+3)=?

(1)若m-3n=2,则m+2-3n/2m-6n=?(2)若2a-3b=2,则4a-(6b+3)=?
m-3n=2‘
所以原式=[(m-3n)+2]/[2(m-3n)]
=(2+2)/(2×2)
=1
2a-3b=2
所以原式=4a-6b-3
=2(2a-3b)-3
=2×2-3
=1

(1)若m-3n=2,则m+2-3n/2m-6n=?
m+2-3n/2m-6n=
=[(m-3n)+2]/2(m-3n)
∵m-3n=2
∴原式=(2+2)/2×2=1


(2)若2a-3b=2,则4a-(6b+3)=?
=4a-6b+3
=2(2a-3b)+3
=2×2+3
=7
