x + 65 = 40 + 60
x + 65 = 100
x = 100 - 65
x = 35
\(x+65=40+60\)
\(x+65=100\)
\(x=100-65\)
\(x=35\)
x + 65 = 40 + 60
x + 65 = 100
x = 100 - 65
x = 35
\(x+65=40+60\)
\(x+65=100\)
\(x=100-65\)
\(x=35\)
x + 65 = 40 + 60
x + 65 = 100
x = 100 - 65
x = 35
\(x+65=40+60\)
\(x+65=100\)
\(x=100-65\)
\(x=35\)
vay x=35
\(x+65=40+60\)
\(x+65=100\)
\(x=100-65\)
\(x=35\)
x + 65 = 40 + 60
40 + 60 = 100
Vay x + 65 = 100
ket qua bang 100 - 65 = 35
x + 65 = 40 + 60
x + 65 = 100
x = 100 - 65
x = 35
x+65=40+60
x+65=100
x=100-65
x=35
Vậy x=35
