7 times a number minus 10 times a number = ???

OpenStudy (anonymous):

\[7x-10x=(7-10)x\]

OpenStudy (anonymous):

make sense?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

since they both have an x you can factor that out \[x(7-10)\]. Next just subtract 10 from 7 \[x(-3)\]

OpenStudy (anonymous):

then multiply back out

OpenStudy (anonymous):

the answer will be -3
