Answer 1

celelalte se rezolva in acelasi mod

Answer 2

1)18+6a=54=>6a=54-18=>6a=36=>a=36:6=>a=6.
2)14+2a=18=>2a=18-14=>a=4:2=>a=2.
3)14+7a=63=>7a=63-14=>a=49:7=>a=7.
4)30+6a=48=>6a=48-30=>a=18:6=>a=3.
5)5+5a=20=>5a=15=>a=3.
6)3a+6=21=>3a=21-6=>a=15:3=>a=5.
7)4a+24=40=>4a=40-24=>a=16:4=>a=4.
8)8+8a=40=>8a=32=>a=32:8=>a=4.
9)15+5a=25=>5a=25-15=>5a=10=>a=2.
10)12+6a=18=>6a=18-12=>a=6:6=>a=1.
11)24+8a= 24=>8a=24:24=>a=8/1
12)m-567=295=>m=295+557=>m=852.
13) nu știu ce e de făcut .
14)m+570=701=>m=701-570=>m=131.
