What is the value of x? 4/5x-1/10=3/19

x=

Step-by-step explanation:

Hi there!

We are given the following equation:

-=

and we need to find the value of x

To do this, we need to isolate the value of x with a coefficient of 1 (1x) on one side. The value of x, or everything else is on the other side

So let's get rid of from the left side by adding to both sides (-+=0).

-=

  +  +

___________

=+

as the fractions on the right side both have the same denominator, we can add them together

=

Now we need to have the value of 1x. Currently we have .

In order to get x with a coefficient of 1, multiply both sides by the reciprocal of , which is

×=*

which simplifies down to

x=

Now reduce the fraction by dividing the numerator and denominator both by 20

x=

Hope this helps!  

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
