x + 300 = 200 x 3 - 100
=> x + 300 = 600 - 100
=> x + 300 = 500
=> x = 500 - 300
=> x = 200
vậy x = 200
x+300=600-100
x+300=500
x=500-300=200 tk nha mik nha nhất!^_^
Giải
x + 300 = 200 x 3 - 100
x +300 = 600 - 100
x + 300 = 500
x = 500 - 300
x = 200
x+300 =200.3-100
x+300 =600-100
x+300 =500
=> x=500 -300
=>x=200
x + 300 = 200 x 3 - 100
x + 300 = 600 - 100
x + 300 = 500
x = 500 - 300
x = 200
Vậy x = 200.
x + 300 = 200 x 3 - 100
x + 300 = 600 - 100
x + 300 = 500
x = 500 -300
x = 200
k cho mình nha
\(x+300=200x3-100\)
\(\Rightarrow x+300=600-100\)
\(\Rightarrow x+300=500\)
\(\Rightarrow x=500-300\)
\(\Rightarrow x=200\)
X + 300 = 200 x 300 - 100
X + 300 = 600 - 100
X + 300 = 500
X = 500 - 300
X = 200
x+300=200x3-100
x+300=600-100
x+300=500
x = 200
