Answer 1

2x-5supra 3=-0.25

2x=-0.25+5/3

2x=-25/100+5/3

2x=-1/4+5/3

2x=17/12

x=17/24

2×17/24-5/3=17/12-5/3=/17-20/12=-3/12=-1/4=-0.25.............

Answer 2

2x-1×3+2/3=0,25
2x-5/3=0,25
2x=25/10+5/3
2x=25/10 il amplificam cu 3 = 75/30
2x=5/3 il amplificam cu 10 = 15/30
2x=75/30+15/30
2x=95/30
X=95/30:2
X=475/15
