Answer 1

[Sahara]

a)\(x+678=7818\)
\(x=7818-678=7140\)
b)\(4029+x=7684\)
\(x=7684-4029=3655\)
c)\(x-1358=4768\)
\(x=4768+1358=6126\)

Answer 2

[Ng KimAnhh]

\(a,x+678=7818\)

\(x=7818-678\)

\(x=7140\)

\(b,4029+x=7684\)

\(x=7684-4029\)

\(x=3655\)

\(c,x-1358=4768\)

\(x=4768+1358\)

\(x=6126\)
