Answer:
the total price of the TV is $840.
Step-by-step explanation:
100% - 30% = 70%
I'm guessing you meant 1,200 not 1.20 (lol) so I'm just going to go with that.
1,200 * 0.70 = 840
Therefore the total price of the TV is $840.

X=14-2y
so, 14-2y+3y=9
y=1
x=14-2*1=12
Hope this answer can help you!
0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
