Question

解方程:5×3-x÷2=8 0.273÷x=0.35 1.8x=0.972 x÷0.756=90 9x-40=5 x÷5+9=21 48-27+5x=31 10.5+x+21=56
还有：x+2x+18=78 (200-x)÷5=30 (x-140)÷70=4
0.1(x+6)=3.3×0.4 4(x-5.6)=1.6 7(6.5+x)=87.5 (27.5-3.5)÷x=4 x+19.8=25.8 5.6x=33.6 9.8-x=3.8 75.6÷x=12.6 5x+12.5=32.3 5(x+8)=102 x+3x+10=70 3(x+3)=50-x+3 5x+15=60 3.5-5x=2 0.3×7+4x=12.5 x÷1.5-1.25=0.75 4x-1.3×6=2.6 20-9x=1.2×6.25 6x+12.8=15.8 150×2+3x=690 2x-20=4
要列式,完整一些,最好：5x-3x=4
2x=4
x=2
