dau coroana facrti si solutiea si calculul scoteti parte intreaga daca se scoate VA ROG FOARTE FOARTE URGENT ^^ MERSI))DAU 20DE PUNCTE

Answer 1

x-2=4, x=6

x+2=-7, x=-9

2x-3x+5=1/2
-x+5=1/2 se aduce la ac.numitor
-2x+10=1
-2x=-9 x=9/2 x= 4 intregi si1/2

1/5x =7 x=35

Si ultimul
7x+5/2=21/5 numitor 10
70x+25=42
70x=17
x=17/70
