Answer:
1/5
Step-by-step explanation:
In order to solve this, you need to simplify. In this case, we would need to distribute first.
-5x - (-7 - 4x) = -2(3x - 4)
-5x + 7 + 4x = -6x + 8
Combine like terms:
-5x + 7 + 4x = -6x + 8
-5x + 6x + 4x = 8 - 7
-x + 6x = 1
5x = 1
X needs to be by itself, so you would divide by 5 (the coefficient in front x) on both sides. So,
5x = 1
x = 1/5

Answer:
Step-by-step explanation:
To calculate the discount, we multiply the initial amount (i) to the discount (d) and then divide that answer by 100. After we find that answer we then subtract it from the initial price.
For example:
A computer costs $695 and it has a 7% discount. Calculate the total costs of the computer after the 7% discount.
The computer (after a 7% discount) costs "$646.35 dollars."
Hope this helps.
