\(280-\left(x-140\right):35=270\)
\(\left(x-140\right):35=10\)
\(x-140=350\)
\(x=490\)
\(280-\left(x-140\right):35=270\)
\(\left(x-140\right):35=280-270\)
\(\left(x-140\right):35=10\)
\(x-140=10.35\)
\(x-140=350\)
\(x=350+140\)
\(x=490\)
\(280-\left(x-140\right):35=270\)
\(\left(x-140\right):35=280-270\)
\(\left(x-140\right):35=10\)
\(x-140=350\)
\(x=490\)
280 - (x - 140) :35 = 270
280 - (x - 140) = 270 . 35
280 - (x - 140) = 9450
x - 140 = 280- 9450
x - 140 = -9170
x = -9170 + 140
x = - 9030
Trả lời:
\(280-\left(x-140\right):35\)\(=270\)
\(\left(x-140\right):35=10\)
\(x-140=350\)
\(x=490\)
Vậy \(x=490\)
Hok tốt!
