24.8-(0.2x+3.5)=1.824.8-(0.2x+3.5)=1.824.8-(0.2x+3.5)=1.824.8-(0.2x+3.5)=1.824.8-0.2x-3.5=1.80.2x=19
24.8-(0.2x+3.5)=1.8
24.8-(0.2x+3.5)=1.8
24.8-(0.2x+3.5)=1.8
24.8-(0.2x+3.5)=1.8
24.8-0.2x-3.5=1.8
0.2x=19.5
x=97.5
0.2x+3.5=24.8-1.8=23
0.2x=23-3.5=19.5
x=19.5/0.2=97.5
难道我理解错了。。。那个x是x次方的意思。。。那只能用计算器了。。。0.2 的1.272次方等于19.5,即x=1.272
24.8-(0.2x+3.5)=1.8
