11x-7x+x=325
5x = 325
x = 325 :5
x = 65
Vậy x = 65
k cho mk nhe

11x - 7x + x = 325
=> 5x = 325
=> x = 325 : 5
=> x = 65
Vậy x = 65

x.(11-7+1)=325
x.5=325
x=325:5
x=65
Nếu mọi người thấy đúng thì tick cho mình nhé!Thanks

a.11x-7x+x=325
<=> 5x= 325
<=> x=65
b.5x+(-15)-3x=25
<=> 5x-3x= 25+15
<=> 2x=40
<=>x=20

a,-15+x=-4 b,35-x=-12-3
x=-4+15 35-x=-12+(-3)
x=11 35-x=-15
vậy x=11 x=35+15
x=50
