316-x=-39 -(-19)

mai phải nộp rùi !

Answer 1

316-x=-39 -(-19)

316-x = 20

x = 316-20

x= 294

Answer 2

316-x=-39 -(-19)

316-x= -20

x=316-(-20)

x=336

Answer 3

\(316-x=-39-\left(-19\right)\)

\(\Rightarrow316-x=-39+19=-20\)

\(\Rightarrow x=316-\left(-20\right)\)

\(\Rightarrow x=316+20=336\)

Answer 4

316-x= ( - 39 ) +19

= - 20

x = 316 - ( - 20 )

x = 316 + 20

x = 336
