Tìm x biết

( 315 - x ) + 264 = 327

( 147 - x ) : 5 = 10

Answer 1

a, 315-x=327-264

<=> 315-x=63

<=> x=315-63

<=>x=252

b, 147-x=10 x 5

<=> 147-x=50

<=> x= 147-50

<=> x=97

Answer 2

\(\left(315-x\right)+264=327\)

\(\left(315-x\right)=63\)

\(x=315-63\)

\(x=252\)

\(\left(147-x\right):5=10\)

\(\left(147-x\right)=50\)

\(x=147-50\)

\(x=97\)

Answer 3

( 315 - \(x\)) + 264 = 327

315 - \(x\) = 327 - 264

315 - \(x\) = 63

         \(x\) = 315 - 63

        \(x\) = 252

(147 - \(x\)) : 5 = 10

147 - \(x\) =10 \(\times\) 5

147 - \(x\) = 50

          \(x\) = 147 - 50

           \(x\) = 97
