Question

tìm x:(253-x):17-7=16

Answer 1

(253-x):17-7=16

(253-x):17 = 16 +7

(253-x):17=23

253-x=23*17

253-x=391

x=253-391

x= -138

Answer 2

\(\left(253-x\right):17-7=16\)

\(\left(253-x\right):17=16+7\)

\(\left(253-x\right):17=23\)

\(\left(253-x\right)=23.17\)

\(\left(253-x\right)=391\)

\(x=253-391\)

\(x=-138\)

Vậy \(x=-138\)
