Answer:
x-y=2.5,xy=21
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
One of the numbers is x.
The other number is y.
The difference between two numbers is 2.5
This means that x - y = 2.5
The product of those two numbers is 21.
This means that xy = 21.
So the two equations are: x-y=2.5,xy=21
Answer:
x=27
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5/3x-4/3x-1=8
5
/3
x+ −4
/3
x+−1=8
(5
/3
x+ −4
/3
x)+ (−1) =8 (Combine Like Terms)
1/3x-1 =8
1/3x=9
(1/3 x) x 3 = 3 x 9
x=27
In order to factor, we must pull out factors common to each term. In this case, each term has factors of 2 and y:
4ay =
2 * 2 * a *
y
2y =
2 *
y
So, we'll pull out the 2y:

To check, distribute the 2y back through the terms in parentheses to ensure you end up with the original expression 4ay - 2y.
