Question

Va rog frumos cu rezolvare

Answer 1

4*(x+5)=28
x+5=28/4
x+5=
x=7-5
x=2

(x-9)/9=81
x-9=81*9
x-9=729
x=729+9
x=738

(x+13)/2=7
x+13=7*2
x+13=14
x=14-13
x=1

7-2x=3
2x=7-3
2x=4
x=4/2
x=2


completez si cu restul
17-(3x+8)=3
3x+8=17-3
3x+8=14
3x=14-8
3x=6
x=6/3
x=2


2(2x-4)-7=5
2(2x-4)=7+5
2(2x-4)=12
2x-4=12/2
2x-4=6
2x=6+4
2x=10
x=5


100/(3x+1)-3=1
100/3x+1=3+1
100/3x+1=4
100=12x+4
12x+4=100
12x=96
x=8


25-(7-2x)=24
7-2x=25-24
7-2x=1
2x=7-1
2x=6
x=3
