✔ 最佳答案
4(a-2)/3+2=64(a-2)/3=4 a-2=3 (全式x3/4)a=5------如果係 4(a-2)/((3+2)=6a-2=15/2 (全式x5/4)a=19/2 or9.5

4(a-2)/3+2=6
4a-8/ 5=6
4a-8=30
4a=38
a=38/4
a=19/2 or 9.5

方程
4(a-2)/3+2=6
4(a-2)/3=6-2
4(a-2)/3=4
4(a-2)=4x3
4(a-2)=12
a-2=12/4
a-2=3
a=3+2
a=5

驗算

以a=5代入原來的方程,
4x(5-2)/3+2
=4x3/3+2
=12/3+2
=4+2
=6

~希望幫到你~^^

4(a-2) / (3+2) = 6
4(a-2) = 6 x 5
4a- 8 = 30
4a= 30+8
4a= 38
a= 38/4
a=19/2

4a- 8 = 30
4a= 30+8
4a= 38
a= 38/4
a=19/2
