只含有一個未知數,並且含有未知數的式子都是整式,未知數的次數是1,這樣的方程叫做一元一次方程。

如:x+(3x-1)=55

x+3x-1=55

4x=56

x=14

7(2x-1)-3(4x-1)=4(3x+2)-1;

(5y+1)+ (1-y)= (9y+1)+ (1-3y);

[ ( )-4 ]=x+2;

20%+(1-20%)(320-x)=320×40%2(x-2)+2=x+1

2(x-2)-3(4x-1)=9(1-x)11x+64-2x=100-9x

15-(8-5x)=7x+(4-3x)

3(x-7)-2[9-4(2-x)]=223/2[2/3(1/4x-1)-2]-x=21 2x-10.3x=15

2 0.52x-(1-0.52)x=80

3 x/2+3x/2=7

4 3x+7=32-2x

5 3x+5(138-x)=540

6 3x-7(x-1)=3-2(x+3)

7 18x+3x-3=18-2(2x-1)8 3(20-y)=6y-4(y-11)

9 -(x/4-1)=5

10 3[4(5y-1)-8]=6

10/3 (x/5+3/7)=9x/2

5/3(x+0.5)+2=3x-6

5x+2(2x/3+2)=2/3(x-6)+2(2x-7)/2-(6x-5)/3=2x+3(3x+2)/5-(x-6)=x/3

6x-(x/3+2)=2(x/5+5/2)-33(x/11-2)-5=2+3x/3

10/3(2x-6)=3/5

x/2-(x/3-2)=3

2/3(x+3)-3=5x/3

5/3(2x-5/3)=2x/5-8/9

25(x/3-x/2+2/5)-2=3/5(x-2/7)+4/9
