Answer:
11 - 4x
Step-by-step explanation:
-5 - 3x - x - (-16)
Reorder the terms so that like terms are next to each other
-5 - (-16) - 3x - x
Combine like terms
11 - 4x
We have y = -2 - 2x ;
Then, x + ( -2 - 2x ) = 5 ;
x - 2 - 2x = 5;
- x - 2 = 5 ;
-x = 7 ;
x = - 7;
Finally, y = - 2 - 2 × ( - 7 ) ;
y = - 2 + 14 ;
y = 12;
<span>The x coordinate of the solution to the system is - 7 .</span>
6(2(5)-4)= 6(10-4)= 6(6)=36 so your answer is 36
! is factorial
it means multipliy all numbers from 1 to that number together
example
1!=1
2!=2*1
3!=3*2*1
etc
some things to note
7!*8=8!
4!*5*6=6!

so we can rewrite it as

=

=
Answer:
4) 7a + 11b
5) i'm not sure
6) 3 (n = 3)
7) i can't see the last ones, but i know that y = 6
i hope this helps
sorry i can't help more :(
Have a great day!
