56−x=28

x=56−28

x=28

x−17=73

x=73 + 17

x=90

\(x\times34+x\times89+x\times24+x\times56=46795\)

\(\Rightarrow x\times\left(34+89+24+56\right)=46795\)

\(\Rightarrow x\times203=46795\)

\(\Rightarrow x=46795:203\)

\(\Rightarrow x=230,5172414\)

Sai đề nha bạn...

Bài làm

X x 34+X x 89+X x 24+X x 56=46795

X x ( 34+89+24+56 ) = 46795

X x 203 = 46795

X           = 46795 : 203

X           = \(\frac{46795}{203}\)

# Chúc bạn học tốt #

~ Mik k chắc là nó đúng ~

\(\dfrac{-3}{7}\)x=\(\dfrac{1}{6}\)

x=\(\dfrac{1}{6}\):\(\dfrac{-3}{7}\)

x=\(\dfrac{7}{-18}\)

x:125=\(\frac{69}{115}\)

x=\(\frac{69}{115}\times125\)

x=75

mình ko biết làm

75nhe

`x xx 95 + x + x : 0,25 = 7963`

`x xx (95 + 1 + 4) = 7963`

`x xx 100 = 7963`

`=> x = 79,63`.

\(x\times\left(95+1+4\right)=7963\)

\(100\times x=7963\)

\(x=79,63\)

\(=>x\left(95+1+4\right)=7963\)

\(x=\dfrac{7963}{95+1+4}=\dfrac{7963}{100}=79,63\)

`x xx95+x+x:0,25=102,34`

`x xx95+x+x xx4=102,34`

`x xx(95+1+4)=102,34`

`x xx100=102,34`

`x=102,34:100=1,0234`

`x xx 95 + x + x :0,25 = 102,34`

`x xx 95 + x + x xx 4 = 102,34`

`x xx ( 95+1+4)=102,34`

`x xx 100 = 102,34`

`x = 102,34 : 100`

`x = 1,0234`

`x xx95+x+x:0,25=102,34`

`x xx(95+1+4)=102,34`

`x xx100=102,34`

`x=102,34:100`

`x=1,0234`
