Question

150X/(1-40%)=150(X+20)/(1-15%)怎么解

要有详细过程，不管是复制粘贴也好，手打也好，截图也好，过程要详细

Answer 1

两边同时除以150： X/0.6=（X+20）/0.85两边同时乘0.6×0.85：0.85X=0.6(X+20) 0.85X=0.6X+0.6×20两边同时减0.6X： 0.25X=12两边同时除以0.25： X=48

Answer 2

原式为：150X/0.6=150(X+20)/0.85 X/0.6=(X+20)/0.85 .0.85X=0.6X+12 0.25X=12 X=48

Answer 3

150x/0.6=150(x+20)/0.85x/0.6=(x+20)/0.850.6(x+20)=0.85x0.6x+12=0.85x0.25x=12x=48

Answer 4

150X/(1-40%)=150(X+20)/(1-15%)x(1-40%)=(x+20)/(1-15%)0.6x=(x+20)/0.85x=- 68

Answer 5

X/0.6=（X+20）/0.850.6（X+20）=0.85X0.6X+12=0.85X0.25X=12X=12÷0.25X=48
