求解决方程,要用小学解方程法：90%x-245=80%x+125
答
90%x-245=80%x+125
90%x-80%x=245+125
0.1x=370
x=3700
答
90%x-245=80%x+125
0.9x-245+245=0.8x+125+245
0.9x=0.8x+370
0.9x-0.8x=0.8x+37x-0.8x
0.1x=370
x=3700
答
90%x-245=80%x+125
10%x=370
x=3700
答
90%x-245=80%x+125
90%x-80%x=245+125
10x%=370
10x=37000
x=3700
答
90%x-245=80%x+125
0.9x-245=0.8x+125
0.9x-0.8x=245+125
0.1x=370
x=370÷0.1
x=3700
