4.x + x = 2035
x.(4 + 1) = 2035
x.5 = 2035
x = 2035 : 5
x = 407
Vậy x = 407
3.(2x + 18) = 504
2x + 18 = 504 : 3
2x + 18 = 168
2x = 168 - 18
2x = 150
x = 150 : 2
x = 75
Vậy x = 75
4.x+x=2035
=>x.(4+1)=2035
=>x.5=2035
=>x=2035:5
=>x=47
3.(2x+18)=504
=>2x+18=504:3=168
=>2x=168-18=150
=>x=150:2
=>x=75
nếu đúng nhớ k nhé đúng @!
4.x+X=2035
X = 2035:4
X=2035/4
B,3.(2X+18)=504
2X+18 =504:3
2X+18 =168
2X =168-18
2X =150
X =150:2
X =75
a)4.x+x=2035
