Question

exercitiul 6 va rog dau coronita!!! + 7, 8 daca le stiti. cine e geniu clik

Answer 1

5/6=7/5/37=5/6=17/5×5/31=5/6=17/13
51/3/6=25/1/2=16/3/6=25/1/2=16/3×1/6=25/1/2=16/18=50/1
1/3=25/73

8)23/x+1=1/4=(x+1)×1=4×23⇒x+1=92⇒x=92-1⇒x=91
x-2/4.5=7.2/1⇒(x-2)×1=4.5×7.2⇒x-2=32.4⇒x=32.4+2⇒x=34.4
3x/2=150/14⇒3x×14=2×150⇒42x=300⇒x=300/42 se simplifica prin 2
x=150/21
