Question

Rezolvati ecuatia :

(1,2x - 3,5 ) inmultit cu 3 +4,25 =5,27

Answer 1

 =>(1.2x-3.5)+3+4,25ori5,27= 3+22,3975=>1,2x-3,5=25,3975=> 1,2x=2+25,3975=>1,2x=27,3975=>x=27,3975impartit cu 1.2 = 22,83125 asa cred ca se face

Answer 2

(1.2x-3.5)*3 +4,25 =5,27
3.6x-10.5+4.25=5.27
3.6x-6.25=5.27
3.6x=6.25+5.27
x=11.52/3.6
x=3.2
