subtract 15mn - 22m + 2n from 14mn - 12m + 7n.\n -mn + 10m + 5n\n -mn - 34m + 5n\n -mn - 34m + 9n\n 29mn - 34m + 9n
Answer
Explanation:
Step1: Write the subtraction expression
$(14mn - 12m+7n)-(15mn - 22m + 2n)$
Step2: Distribute the negative sign
$14mn - 12m+7n - 15mn+22m - 2n$
Step3: Combine like - terms for $mn$ terms
$(14mn-15mn)=-mn$
Step4: Combine like - terms for $m$ terms
$(-12m + 22m)=10m$
Step5: Combine like - terms for $n$ terms
$(7n-2n)=5n$
Step6: Write the final expression
$-mn + 10m+5n$
Answer:
$-mn + 10m+5n$
