Question

大家忙我做10道方程题,
10y+2(7y-2)=5(4y+3)+3y
3/4[4/3*（1/2x-1/4)-8]=3/2x
(x+1)/2-(5+x)/6=3-(x-1)/3
(0.2-x)/0.3-1.5=(1-3x)/2.5
6x=6-5(2-2x)
2(10-0.5y)=-(1.5y+2)
y-(y-3)/2=y/6+7/2
(5y+4)/3+(y-1)=2-(5y-5)/12
(4x-1.5)/0.5-(5x-0.8)/0.2=(1.2-x)/0.1
(x+1)/0.3-2x=(0.1x+0.2)/0.05

Answer 1

10y+2(7y-2)=5(4y+3)+3y
10y+14y-4=20y+3y+15
24y-23y=19
y=19
6x=6-5(2-2x)
6x=6-(10-10x)
6x=6-10+10x
6x-10x=6-10
-4x=4
x=-1
2(10-0.5y)=-(1.5y+2)
20-y=-1.5y+2
20-2=y-1.5y
18=-0.5y
y=-36
3/4[4/3*（1/2x-1/4)-8]=3/2x
1/2x-1/4-6=3/2x
2x-1-24=6x
-4x=25
x=-25/4
(x+1)/2-(5+x)/6=3-(x-1)/3
3(x+1)-(5+x)=18-2(x-1)
3x+3-5-x=18-2x+2
4x=22
x=11/2
其他不会了.答这两题都累死我了,不好意思.
