(1)(3x-5y)-(6x+7y)+(9x-2y)
=3x-5y-6x-7y+9x-2y (正确去掉括号)
=(3-6+9)x+(-5-7-2)y (合并同类项)
=6x-14y
(2)2a-[3b-5a-(3a-5b)] (应按小括号好句1)(4a²b-10b³)+(-3a²b²+10b³) =4a²b-3a²b²+10b³-10b³=a²b².
(2) (4x²y-5xy²)-(3xy²-4xy²) =4x²y-5xy²-3xy²+4xy²=4x²y-4xy²=4xy(x-y).
3) 5a²-[ a²+(5a²-2a)-2(a²-3a)] =5a²-[ a²+5a²-2a-2a²+3a] = 5a²-[ 4a²+a] = 5a²-4a²-a=a²-a.
4)15+3(1-a)-(1-a-a²)+(1-a+a²-a³)=15+3-3a-1+a+a²+1-a+a²-a³=18-3a+2a²-a³.
(5) (4a²b-3ab)+(-5a²b+2ab)=4a²b-3ab-5a²b+2ab=-a²b-ab

(2)(2x / x ² -y ² )+(3x / y ² -x ² )+【x / (x+y)(y-x)】
=2x/(x²-y²)-3x/(x²-y²)-x/(x²-y²)
=(2x-3x-x)/(x²-y²)
=-2x/(x²-y²)
(3)(x ² -x-2 / x+3)÷(2-x)+(x+1 / x+3)
=(x²-x-2)/(x+3)(2-x)+(x+1)/(x+3)

=0∵-2x3m+1y2n与7xn-6y-3-m的积与x4y是同类项,描写

∵2小时有4个30分钟,好句
∴3×24=3×16=48.
故答案为:48.描写∵3×27^(n-1)×81^(n-1)=3×3^(3n-3)×3^(4n-4)=3^(7n-6)=3^49
∴7n-6=49
∴n=55 ∕ 7
5x‐\9=n(x﹢1)=55(x﹢1) ∕ 7
35x‐\63=55x﹢55
x=‐\5.9

∵3×9m×27m,好句
=3×32m×33m
=31+5m
∴31+5m=316
∴1+5m=16,
解得m=3.∵3÷3060=6(次),描写
∴1个分裂26=64个.
故答案为:64
