Question

реши уравнение 
 
6*x+8=14+30
5*(x+4)-43=17
20+4*x=52

Answer 1

6Х + 8 = 14 + 30
6Х = 44 - 8 
6Х = 36 
Х = 6 
-------------
5*( X + 4) - 43 = 17 
5X + 20 - 43 = 17 
5X = 17 + 23
5X = 40 
X = 8 
--------------
20 + 4X = 52 
4X = 32 
X = 8

Answer 2

1)6*x+8=14+30
6*х+8=44
6*х=44-8
6*х=36
х=36:6
х=6
2)5*(x+4)-43=17
5*(х+4)=17+43
5*(х+4)=60
х+4=60:5
х+4=12
х=12-4
х=8
20+4*x=52
4*х=52-20
4*х=32
х=32:4
х=8
