X - 70 = 100 + 50
X - 70 = 150
X = 150 + 70
X = 220
\(x-70=100+50\)
\(x-70=150\)
\(x=150+70\)
\(x=220\)
tk mk nha bn
\(x-70=100+50\)
\(x-70=150\)
\(x=150+70\)
\(x=220\)
Ta có: x - 70 = 100 + 50
=> x - 70 = 150
=> x = 150 + 70
=> x = 220
Vậy x = 220
k cho mk nha!
X - 70 = 100 + 50
x - 70 = 150
x = 150 + 70
x = 220
X - 70 = 100 + 50
X - 70 = 150
X = 150+ 70
X = 220
X - 70 = 100 + 50
X - 70 = 150
X = 150+ 70
X = 220
