Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
find out how much you earn per minute 2000/10=200
in an hour there are 60 minutes.
multiply the amount earned in a minute by the amount of minutes.
200*60=12000
So you earn $12,000 per hour
Wooow I wish I could earn that much
Answer:
x=-9
Step-by-step explanation:
5x+1=7x+19
1 = 7x-5x +19
1-19 = 2x
-18/2 = x
x = -9
