Answer:
J=38
Step-by-step explanation:
Subtract 7 to both sides so J/-2=-19
Then multiply -2 to both sides to get -19 times -2
That equals to 38
The graph shows the solution to be (x, y) = (-1, 3).
The amount of the discount is $7.59
First add 1 to each side. It will leave you with an equation like this. 5x=3x -4
Next, subtract 3x from each side. It will leave you with an equation like this. 2x= -4
Lastly, divide each side by 2 so we can get x by itself.
ANSWER: x=-2
