tolong di jawab yaa. dari a sampai e. terima kasih

A. 6x + 5 = 26 - x
6x + x = 26 - 5
5x = 21
x = 21/5
= 4,5.
Bismillah gatau bener gatau ngga..

a.) 6x+5= 26-x
6x+x = 26-5
7x = 21
x=3

b.) 2-4x = 3
4x = 2-3
4x = -1
x = -1/4

c.) x-12= 2x +36
x-3x = 30+12
-2x = 42
x = -21

d.) -5x-4x+10 = 1
-9x = 1-10
-9x = -9
x = 1

e.) 2+x/4= 5
x/4 = 5-2
x/4 = 3
x = 12

maaf kalau ad yang salah,,,
