Answer:

7: (3,9) 8:(-2,1) 6: (2,10)

Step-by-step explanation:

7) 2x+3=-2x+15

x=3

y=2(3)+3

y=6+3

y=9

8)x= -1(1+2y)/3

-4-2y=-6

y=1

x=-2(1+2(1))/3

x=-2

6)2x-16=-12

x=2

y=2+8

y=10

The given equation has no solution when C is equal to what number?<br><br> 2x+C(8+x)=16

3241004551 [841]

Answer:

$-2$

Step-by-step explanation:

When $C=-2$ , the variable $x$ will be removed from the equation ( $2x-2x=0$ ). Therefore, we are left with $-16\neq 16$ . Thus, when $C=-2$ , the given equation has no solutions.
