X + X + X + X = 80 X 25
X + X + X + X = 2000
4 X = 2000
X = 2000 : 4
X = 500
Tk Đúng cho mk nhé ! ^^
x + x + x + x = 80 x 25
x + x + x + x = 2000
x * 4 = 2000
x = 2000 : 4
x = 500
X+X+X+X=2000
Xx4 =2000
X =2000:4
X =500
k mình nha
X+X+X+X= 80x25
X+X+X+X=2000
4xX = 2000
X = 2000 :4
X = 500
x + x + x + x = 80 x 25
4x = 2000
x = 2000 : 4
x = 500
Vậy x = 500
x + x + x + x = 80 x 25
4x = 2000
x = 2000 : 4
x = 500
Vậy x = 500
x + x + x + x = 80 x 25
4x = 2000
x = 2000 : 4
x = 500
Vậy x = 500
x + x + x + x = 80 x 25
4x = 2000
x = 2000 : 4
x = 500
Vậy x = 500
