Câu 3: 

a: y=-3

=>-1/2x=-3

hay x=6

like cho mình nhé

a) \(\left(-189\right)+135+\left(-111\right)+\left(-135\right)\)

\(=\left(-189-111\right)+\left(135-135\right)\)

\(=-300+0\)

\(=-300\)

b) \(126+345-126+215\)

\(=\left(126-126\right)+\left(345+215\right)\)

\(=0+560\)

\(=560\)

c) \(\left(-213\right)+186+\left|-213\right|-186+100\)

\(=\left(-213\right)+186+213-186+100\)

\(=\left(-213+213\right)+\left(186-186\right)+100\)

\(=0+0+100\)

\(=100\)

d) \(\left(-34\right)+\left|-123\right|+\left|-34\right|-123+200\)

\(=\left(-34\right)+123+34-123+200\)

\(=\left(-34+34\right)+\left(123-123\right)+200\)

\(=0+0+200\)

\(=200\)

e) \(\left(-250\right)+\left(-15\right)-\left(-250\right)+\left|-15\right|+150\)

\(=\left(-250\right)+\left(-15\right)+250+15+150\)

\(=\left(-250+250\right)+\left(-15+15\right)+150\)

\(=0+0+150\)

\(=150\)

Ai xong trước và đúng thì mik nhé😇😇😇😇😇🥺🥺😭😫😫
