方程(x÷90+0.5)=(x÷60-0.5)怎么解

(x÷90+0.5)=(x÷60-0.5)
x/90+0.5=x/60-0.5
x/60-x/90=1
x/180=1
x=180可以问这一段x/60-x/90=1x/180=1怎么得的吗?我还是小学的阶段,不太懂多少(x÷90+0.5)=(x÷60-0.5)(x÷90=x/90;x÷60=x/60) (x÷90+0.5)=(x÷60-0.5)x/90+0.5=x/60-0.5(移项,把带有x项移到一边,把数字移到一边)x/60-x/90=0.5+0.5(等式左边通分)3x/180-2x/180=1x/180=1(现在能看懂了吗?)x=180
