Question

Tính y biết: y × 123 - y × 10 = 710000 hãy giúp tớ với

Answer 1

y x 123 - y x 10=710000
y x (123-10)=710000
y x 113=710000
y =710000:113
y=6283(dư 21)

Answer 2

\(y\times123-y\times10=710000 \)

\(\Rightarrow y\times\left(123-10\right)=710000\)

\(\Rightarrow y\times113=710000\)

\(\Rightarrow y=710000:113\)

\(\Rightarrow y=.........\)
