\(x+200-\left(-100\right)-150=250+2.50\)
\(x+200+100-150=250+100\)
\(x+150=350\)
\(x=350-150\)
\(x=200\)
x+200-(-100)-150=250+2.50
x+200+100-150=250+100
x+200+100-150=350
x+200+100 = 500
x+200 = 400
x =200
vậy x=200.
x+200-(-100)-150=250+2.50
x+200-(-100)-150=250+100
x+200-(-100)-150=350
x-(-100)-150=350-200
x-(-100)-150=150
x-(-100)=150+150
x-(-100)=300
x=300+(-100)
x=200
x+200-(-100)-150=250+2.50
x+200+100-150=250+100
x+200+100-150=350
x+200+100 = 500
x+200 = 400
x =200
x + 200 - ( -100 ) - 150 = 250 + 2.50
x + 200 - ( -100 ) - 150 = 250 + 100
x + 200 - ( -100 ) - 150 = 350
x - ( -100 ) - 150 = 350 - 200
x - ( -100 ) - 150 = 150
x - ( -100 ) = 150 + 150
x - ( - 100 ) = 300
x = 300 + ( -100 )
x = 200
