1. x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
2. y=2(7)-3.5
y=14-3.5
y=10.5
hope this helps!

You plug the equation that equals y into the y value on the other equation that equals 4. Then, you plug the x value into the x on the equation that equals y. Sorry if that was confusing
If you are rounding to the nearest tenth then yes
If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...
30% * x = 120
.30x = 120
x = 120/.30
x = 400
The original cost was $400
So you must find individual prices.
Start by doing the price($2.00)divided by the amount in box(8)
you should get 0.25 or 25 cents per chocolate
