(8+9)x+72=98怎么算

(8+9)x+72=98 17x+72=98 17x=98-72 17x=26 x=26÷17 x=26/17

98×36+72 =98×36+2×36 =(98+2)×36 =100×36 =3600

(72-8)x(9÷3) =64*3 =192

采纳吧

解:依题意得算式, x-2÷8+3×9=72 x-0.25+27=72 x+26.75=72 x=72-26.75 x=45.25 即x-2÷8+3×9=72的解是x=45.25

解方程(后两小题写出验算过程).75x-0.95×4=8.554÷2+3x=72     8x-2.6x=37.8.

=72×(72÷9) =72×8 =576

8*9*0.125 =8*0.125*9 =1*9 =9 请采纳◑▂◑

(x-1)x=72 x^2-x-72=0 (x-9)(x+8)=0 x-9=0或x+8=0 x=9 或 x=-8

(32+X)/(72+X)=9/19 9(72+x)=19(32+x) 648+9x=608+19x 19x-9x=648-608 10x=40 x=4
