Question

how do i do -2(5u-v)-v

Answer 1

foil

Answer 2

but what happened to the u

Answer 3

sorry I think all is v

Answer 4

-10u+2v-v= -10u +v

Answer 5

?

Answer 6

cali....first simplify the left side first to get -10u + v = -10u + v you'll see these are the same

Answer 7

so in this case, the answer is "all real numbers" or "infinitely many solutions" because the equations are the same....

Answer 8

\[-2(5u-v)-v\]
\[-10u+2v-v\]
\[-10u+v\]

Answer 9

that is if it is u and v. if it is all u then
\[-2(5u-u)-u\]
\[-2(4u)-u\]
\[-8u+u\]
\[-7u\]
