x + 10 = 15 x 2
x + 10 = 30
x = 30 - 10
x = 20
x +10 = 30
=> x = 30 - 10
=> x = 20
Tổng là:
x + 10 = 15 x 2
x + 10 = 30
x = 30 - 10
x = 20
Vậy x = 20
x + 10= 13 x 2
x + 10=30
x=30 -10
x=20
\(x+10=15\cdot2\)
\(\Rightarrow x+10=30\)
\(\Rightarrow x=30-10\)
\(\Rightarrow x=20\)
Vậy: \(x=20\)
\(x+10=15x2\)
\(x+10=30\)
\(x=30-10\)
\(x=20\)
x + 10 = 15 * 2
x + 10 = 30
x = 30 - 10
x = 20
