Question

4+(1÷8)X=4.5(X-3) 求如何解此方程..答得好有更多悬赏.... 快点...10分钟内给我做出来...

Answer 1

方程两边同时乘以8，得：32+X=36(X-3)
32+X=36X-108
32+108=36X-X
140=35X
两边同时除以5，得： 4=X 即：此方程的解为X=4

Answer 2

4+(1÷8)X=4.5(X-3)
4+x/8=4.8x-13.5
4+13.5=4.8x-x/8
17.5=4.8x-0.125x
17.5=4.675x
x=700/187
希望对你有帮助

Answer 3

解：4+(1÷8)X=4.5(X-3)
4+(1/8)x=(9/2)x-4.5×3
(1/8)x-(9/2)x=-13.5-4
-(35/8)x=-35/2
x=4

Answer 4

4+1/8*x=4.5*x-4.5*3
4+4.5*3=4.5*x-1/8*x
4.375*x=17,。5
x=4
