Answer:

x= -20

Step-by-step explanation:

So the first thing you would want to do is multiply 2 on both x and -50. After that you will end up with 7x = 2x - 100. Then you will need to subtract x on both sides getting 5x = -100. Finally you will need to divide 5 on both sides getting x = -20

the sale price of an iphone is 179.00. if the percent discount was 20% what was the original price of the iphone?
Tju [1.3M]
100 - 20 = 80
179.00 = 80%
179.00 / 80 = 2.2375 = 1%
1% x 100 = 100%
So, 2.2375 x 100 = 100%
Therefore the original price was 223.75
