Answer 7

i think

-2×5 -7 = ?
make sense

Answer 8

i ws just making sure, as if it is the 1st one, we will have a little more stepsthan the 2nd one as we had to equalise it all by 0 and blla blla-- butlets go with the 2nd one haha

so we have got \(-2 \times5-7\)

we first have to do the multiplication, so it will look like this
\[ (-2 \times5)-7 \]

what is negative two times 5?

Answer 9

NOTE: \( (-)\times(+)= (-) \)

Answer 10

I don't know

Answer 11

-2x5=-10

Answer 12

its simple!

we said that \( (-)\times(+)= (-) ​\)

now lets just multiply the numbers as we would usually do:
\( 2\times5=10 \)
adding the negative sign, we get \( -10 \)

so we're left with: \( -10-7=x ​\)

that is the same as writing \( (-10)+(-7)=x \)

what is x?
