Question

tìm x 

x×409=86265

x×12+95=239

89658:x=293

x:125=130

66178:x=326

 

Answer 1

\(x\cdot409=86265\)

\(x=86265:409\)

\(x=\frac{86265}{409}\)

\(x\cdot12+95=239\)

\(x\cdot12=144\)

\(x=144:12\)

\(x=12\)

\(89658:x=293\)

\(x=896568:293\)

\(x=\frac{89658}{293}\)

\(x:125=130\)

\(x=125\cdot130\)

\(x=16250\)

\(66178:x=326\)

\(x=203\)

Answer 2

tìm x 

x×409=86265

x = 86265 : 409 

x = 86265/409

x×12+95=239

x × 12 = 239 - 95 

x × 12 = 144 

x = 144 : 12 

x = 12

89658:x=293

x = 89658 : 293 

x = 306

x:125=130

x = 130 × 125 

x = 16 250

66178:x=326

x = 66178 : 326 

x = 203
