3.) 2x = 3(5 - x)

Tolong ya..

Answer 1

1)4n=-16
n=-4
2)3x+4=2x+22
3x-2x=22-4
x=18
3)2x=15-3x
2x+3x=15
x=3
Semoga membantu,Jadikan yg terbaik thx :)

Answer 2

4n + 5 = -11
4n = -11 - 5 
4n = - 16
n = -4 

3x + 4 = 2 ( x + 11 )
3x + 4 = 2x + 22
3x - 2x = 22 - 4
x = 18 

2x = 3 ( 5 - x )
2x = 15 - 3x 
2x + 3x = 15
5x = 15 
x = 3
