解方程:x-5/3+x+5/8=x-3/4+2x+3/9(x-5)/3+(x+5)/8=(x-3)/4+(2x+3)/9
解方程:x-5/3+x+5/8=x-3/4+2x+3/9
(x-5)/3+(x+5)/8=(x-3)/4+(2x+3)/9

解方程:x-5/3+x+5/8=x-3/4+2x+3/9(x-5)/3+(x+5)/8=(x-3)/4+(2x+3)/9
(x-5)/3+(x+5)/8=(x-3)/4+(2x+3)/9
24(x-5)+9(x+5)=18(x-3)+8(2x+3) (去分母)
24x-120+9x+45=18x-54+16x+24 (去括号)
33x-75=34x-30
x=-45

负45
