Answer:
you need to tell us what error she made first then you would find another way to solve the problem and look at all the posiibiltys
Step-by-step explanation:
Answer:The constant of proportionality is represented by x.
Hope this helps.
2d +9= 19
The solution is d =
Hello there, first we can place our equation, which you have stated
, this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.
First we can subtract 
with both sides of the equation giving us the result of 
, this can also be represented as 
, now just divide both sides of the equation by 
, our answer is 
.

Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
Answer:
Step-by-step explanation:
We can let the 'number' in the expression be equal to 
. Something 6 less than x would x minus 6, or .
