Question

Simplify by combining like terms. -8m+11n+6+5m-9n-10+y

Answer 1

lets group them together first
\[-8m+5m+11n-9n+6-10+y\]

Answer 2

now combine
since \(-8+5=-3\) we get \(-3m\)
since \(11-9=2\) we have \(2n\)
also \(6-10=-4\) and \(y\) has no match
that gives
\[-3m+2n-4+y\]

Answer 3

Thank you @satellite73

yw, with practice you do this with you eyeballs, no need to rearrange

Answer 5

btw kudos to your teacher (or book) for writing "simplify by combining like terms" and not just "simplify"
