Answer 1

Răspuns:

Explicație pas cu pas:

1,3*x+2,73=2*(1,2*x-1)

=$\frac{13}{10} x+\frac{273}{100} =2*(\frac{12}{10} x-1)\\\\\frac{130}{100} x+\frac{273}{100} =2*(\frac{120}{100} x-\frac{100}{100} )\\\\\\130x+273=240x-200\\273+200=240x-130x\\110x=473\\x=4,3\\\\\\\frac{x}{2} +\frac{4}{9} =\frac{x+7}{6}$
