Rezolvati ecuatiile: a) 144:x+5=13,b)15-153:x=6,c)182:x-11=15,d)2×(4x-1)=14,e)16×(2x-3)=8x,f)12×(x-1)=24. va rog mult,dau coronita

Răspuns :

a)144:x+5=13=>144+5-13=x=>136=x
b)15-153:x=6=>x=6-15+153=>x=-162
c)182:x-11=15=>x=15-182+11=182-26=>x=146
d)3•(4x-1)=14=>8x-2=14=>x=16/8=2
e)16•(2x-3)=8x=>32x-48=8x=>32x-8x=48=> 48/24=6/3=2
f)12•(x-1)=24=>12x-12=24=>12x=24+12=>x=36/12=6/2=3
