39x-3y=21
-3y=21-39x
(subtract both sides of the equation by 39x and divide both sides by -3)
y=-7+3x : would be the equation for y.

Pants are 25% if pants are $50 what is the new price
Contact [7]

Answer: $37.50

Step-by-step explanation: Assuming you mean 25% off and not 25% of the original price, first convert 25% to a decimal by dividing by 100. 25%/100=0.25. Multiply the price by 0.25. 50*0.25=12.5. Subtract the discount from the original price. 50-12.5=37.5.

One number is five less than a second number. Three times the first is 14 more than 4 times the second. Find the numbers.
Evgen [1.6K]

Answer:

Second number = -29

First number  = -34

Step-by-step explanation:

Second number = x

First number  = x - 5

3*(x-5) = 4x + 14

3x - 3*5 = 4x + 14

3x - 15  = 4x + 14

      -15 =  4x +14 - 3x

      -15 = x + 14

-14 - 15 = x

x = -29

Second number = -29

First number  = -29 - 5 = -34
