Step-by-step explanation:
let c = # of cheeseburgers
let h = # of hamburgers
c = 2h (The number of cheeseburgers sold was two times the number

3h = 381
h = 127
-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7

-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
