Question

x * 199 - x * 75 = 12648

mình cần gấp

Answer 1

\(x\times199-x\times75=12648\)

\(\Leftrightarrow x\times\left(199-75\right)=12648\)

\(\Leftrightarrow x\times124=12648\)

\(\Leftrightarrow x=12648:124\)

\(\Leftrightarrow x=102\)

Answer 2

x*199-x*75=12648

=>x*(199-75)=12648

=>x*124=126488

=>x=12648/124

=>x=102

Answer 3

\(x\times199-x\times75=12648\)

\(x\times\left(199-75\right)=12648\)

\(x\times124=12648\)

\(x=12648:124\)

\(x=102\)
